Dowsing and Curry Lines
an Electromagnetic Phenomenon
1 Introduction
It’s a well-known fact that dowsers react to some kind of radiation from the earth; this radiation is sometimes called earth-rays. The German doctor, Manfred Curry, demonstrated that the earth is surrounded with a radiation field that forms a grid of lines with approx. 4 m distance. This radiation field is called curry lines in Scandinavia and Germany. I will use the expression curry lines in the rest of this article.
What is the physical phenomenon behind curry lines and dowsing? I will show that the physical phenomenon that creates curry lines is a static slowly varying electromagnetic field. Curry lines can be measured or detected by means of pendulum and L- rods (dowsing). The human body and its muscles reacts on the electromagnetic field in the curry lines and the pendulum or L-rods will respond. It has not been possible to detect or measure curry lines with electrical or magnetic instruments.
It is well known from the literature that you can have the same reaction, i.e. response on the pendulum or L-rods if you pass an electromagnetic field (ex. power line). I have made a number of measurements with pendulum and L-rods on a static electromagnetic field. In all these measurements I get exactly the same result as I get when I measure the field from a curry line. I can add a static electromagnetic field to the field from a curry line, depending on the phase of the electromagnetic field the two fields will cease or be amplified. All results from measurements I make on electromagnetic fields and curry lines are identical, as well as measurements of a mixed electromagnetic and curry line field. From this I draw the conclusion that the field from curry lines is a static electromagnetic field.
2 Experiments with electromagnetic fields
The purpose with these experiments is to show that a static electromagnetic field creates exactly the same phenomenon as the field from a curry line. I create the static electromagnetic field with DC current led through a conductor (copper wire); this creates a circular electromagnetic field along the wire. I measure the electromagnetic field from the wire in the same way as I measure curry lines, i.e. with pendulum or L- rods (I prefer L-rods). Those who are not familiar with how curry lines are measured or how to handle pendulum or L-rods I recommend to read articles on the web (search on dowsing).
2.1 The electromagnetic field from a conductor or wire
Place the conductor/wire (I use a 10 meter insulated copper wire) in a 2-meter straight line on the ground (or the floor if you prefer to measure in your home). The wire should not be placed close to a curry line. The rest of the wire is placed in a coil so that its two ends meet. Attach the two ends to a DC current generator (you can use a 12 Volt battery and a variable resistor). Adjust the current to 0.5 A (Ampere). When I pass (walk over) the wire my L-rods will respond in exactly the same way as when I pass (walk over) a curry line. I get the same result with a pendulum, i.e. its motion will cease. I can decrease the current below 0.001 A (1 mA) and still measure the field.
Conclusion: our body is sensitive to a static electromagnetic field and we can detect it by means of pendulum or L-rods.

2.2 To extinct or damp the electromagnetic field
Place a new wire in parallel with the wire in above experiment without closing its two ends. I will detect the electromagnetic field as before. If I connect the two ends (short circuit the wire) the L-rods will not respond, I can no longer detect the field. This is in accordance with physical laws; the electromagnetic field from the first wire generates a current in the second wire, which in its turn generates an electromagnetic field with opposite phase. The two fields will interact and cease (extinct).
When I open the two ends of the second wire I will once again detect the field with my L-rods. Its’ interesting to notice that when I close the two ends of the second wire my L-rods will respond when I pass that wire on a place where it’s not in parallel with the first wire. This is because the generated current creates an electromagnetic field in the second wire.
2.3 The electromagnetic field from a crossing wire
Place the wire so that it crosses itself, i.e. make an approximately 2 meter straight line, make a 90-degree coil and then a straight line that crosses the first line. The wire makes a cross, see to that this cross is not close to a curry line cross, i.e. where two curry lines are crossing. Adjust the DC current to 0.5 A. Place a medium large iron object (5 kg) on the wire cross. You will experience an amazing phenomenon. Walk in a circle (1 meter radius) around the object. The L-rods respond at 16 places, i.e. when I pass the wires at 4 places and at 12 additional places. I measure this in a methodical way and mark the places where the L-rods respond with a match or a small plastic object. These objects will form an interesting pattern that looks very much like a sunflower with a circle at the outer edge. Close to the wire cross I will measure a field that forms a circle around the cross (the inner part of the sunflower). Outside this circle I will measure 16 radial fields that will bend and connect to the outer circle, it looks like 16 petals.
The crossing wire has created two crossing electromagnetic fields; these fields interact with the matter (its molecules or atoms) in the stone and create an electromagnetic interference pattern. If I remove the stone the interference pattern will disappear.


2.3.2 The size of the interference pattern is proportional to the field strength
I repeat the above experiment but vary the DC current from 0.001- 1.0 A. For every current setting I measure the radius of the interference pattern. In the interval between 0.1 and 1.0 A the radius is proportional to the current, i.e. proportional to the strength of the electromagnetic fields. In the interval between 0.001-0.1 A the size of the pattern decreases slowly and I can detect the field at a current lower than 1 mA.

2.3.3 The size of the interference pattern is proportional to the mass
In the following experiment I keep the current constant (0.5 A) and vary the mass of the object placed on the crossing wire. I use a bucket and fill it with 1 liter of water, 2 liters, 3 liters etc. I measure the radius of the interference pattern each time. I place one iron ball, two iron balls, three iron balls on the wire cross and my son (40 kg), my wife (65 kg) and my son and wife (105 kg) on the wire cross. In all cases the size of the interference pattern is proportional to the mass of the object.
3 Experiments with curry lines
In the following experiments I will show that the field from a curry line will create phenomenon that are identical to those from an electromagnetic field. I will recreate the experiments I show in chapter 2, but use the field from a curry line instead of an electromagnetic field.
3.1 Place a stone, a bucket of water or a human being on a curry cross
A curry cross is the place where two curry lines cross. When I place a stone, a bucket of water or a human being on a curry cross I will detect exactly the same interference pattern as I show in chapter 2.3. The size of the pattern is proportional to the mass of the object as in 2.3.3. I get exactly the same result, as in chapter 2.3.1, i.e. the same matter will create an interference pattern.
Conclusion: two crossing electromagnetic fields and two crossing curry lines (fields) will create exactly the same interference pattern (electromagnetic field) and they interact with exactly the same matter. It is tempting to believe that the curry line is an electromagnetic field. Let’s see if we can find more similarities.
3.2 Create a cross consisting of one curry line and one electromagnetic field
I place the wire (DC current 0.5 A) perpendicular to a curry line, in this way I create a cross consisting of one curry line and one electromagnetic field. I place the same objects on the cross as in above experiment (chapter 3.1). I detect exactly the same interference pattern; the size is proportional to the mass of the object and proportional to the DC current.
Conclusion: a curryline and an electromagnetic field will interact as if they where two electromagnetic fields or two curry lines.
3.3 Extinct or damp a curry line
I place a wire in parallel with (on top of) a curry line. I let the rest of the wire make a coil so that the two ends meet. Short circuit the two ends, i.e. create a closed electrical circuit. If I walk over (pass) the curry line my L-rods will not respond. The closed electrical circuit has absorbed the curry line (field). If I walk over (pass) the wire at a place outside the curry line my rods will respond.
Conclusion: the curry line (field) behaves as if it is an electromagnetic field. This field generates an electric current in the wire; this current generates an electromagnetic field around the wire in opposite phase to the curry line field. The two fields interact and cease (extinct).

3.4 Add an electromagnetic field to a curry line
I place the wire in parallel (on top of) a curry line and adjust the current to 0.5 A. This current works for me but it can be individual and depend on the physical location so you have to adjust the current to your individual need. I have now added an electromagnetic field to a curry line. If the phase of the electromagnetic field is correct my L-rods will not respond, i.e. the two fields have extinct each other. I can change the phase of the electromagnetic field by connecting the two wire ends to the opposite poles of the current generator. If I change the phase, my L-rods will respond again because the two fields are in phase.
In the next experiment I let the electromagnetic field have the same phase end repeat my measurement (walk across the wire) every minute during one hour. What I measure is that the field will disappear during 3.5 minutes, appear during 3.5 minutes, then disappear during 3.5 minutes, appear during 3.5 minutes etc. The cause of this is that the field from the curry line changes phase (180 degrees) with a period of approx. 7 minutes. The field from the curry line is a slowly varying field but it varies so slowly that in most cases it will appear as static.
I repeat this experiment by placing the wire on top of a curry cross and an object on top of that. I then detect exactly the same interference pattern as described in chapter 2.3 but the pattern will appear and disappear in intervals of 3.5 minutes. If the object is large I can detect this pattern 30 meters away. This means that I can, indirectly, detect a modest DC current of 0.5 A at 30 meter distance.
3.5 Extinct or damp the curry line with a capacitor
In chapter 3.3 I describe how it is possible to damp or extinct a curry line with a wire with a short circuit. I will now repeat this experiment but instead of a short circuit I connect the two wire ends to a capacitor (approx. 10 nF), i.e. I make a closed circuit with the capacitor in series with the wire. My L-rods will not respond; the field from the curry line has ceased. After approx. one minute my L-rods will respond again, the field from the curry line has appeared again. The explanation is that when I connect the capacitor to the wire the capacitor is initially discharged. The curry line (field) generates a current in the wire and the capacitor constitutes a short circuit, I can’t detect the curry line. This current charges the capacitor and when the capacitor is fully charged the wire circuit is open, I can then detect the curry line.
Conclusion: This experiment proves that the field from the curry line is static or varies very slowly. If the field alternates with medium to high frequency the capacitor would form a continuous short circuit, the field from the curry line would be damped continuously.

4 Three-dimensional patter
The interference pattern I describe in chapter 2.3 is three-dimensional. I repeat the experiment in chapter 2.3 and place the wire cross and the object on the GROUND floor in my house and measure the interference pattern. If I move to the basement I will measure exactly the same patter straight below the pattern on the ground floor. If I move to the second and third floor I will measure exactly the same patter straight above. It’s looks like a long cylinder with the sunflower pattern inside.
I now change the experiment somewhat. I take a cubic iron object (each side approx. 1dm) and attach a small wire cross to its side with Scotch tape. In the earlier experiment the wire cross was placed in the horizontal plane. In this experiment the wire cross is flipped 90 degrees so that it’s placed in the vertical plane. I can now detect the interference pattern as a long cylinder in the horizontal plane. It is like a long beam or ray that propagate (perpendicular) from the wire cross. When I twist the wire cross to the side the beam will change direction, always perpendicular to the wire cross. I can tilt the wire cross somewhat upwards and detect the beam on my second floor. I can decrease the DC current in the microampere range and still detect the beam 10 meters away. When I place a copper or iron shield in front of the beam it will deflect 90 degrees to the side.
Our body is sensitive to an electromagnetic field; this reaction makes the L-rods respond (a small muscular reaction influence the L-rods). I expected the sensitive area of the body to be in the brain. It’s not. In the above experiment its possible to position the beam very exactly, by reducing the DC current it’s also possible to narrow down the diameter of the beam to 1-2 decimeters. I then place the wire cross on different heights, i.e. the beam radiates at different heights. When I direct the beam towards my head or my chest the L-rods don’t respond. Directed towards my belly the L-rods respond.
Conclusion: the centre for electromagnetic sensitivity is in or close to the belly.
5 Interference pattern in the nature
The interference pattern (sunflower pattern) that I describe in chapter 2.3 can be found in the nature, at least in Sweden where I live. In Sweden there are two Viking graves that are well known to dowsers. The Viking graves, Uppsa Kulle outside the city of Nykoping and Anundshogen outside the city of Vasteras are both famous for their strong currylines.
It’s a well known fact that these curry lines form a pattern that is very similar to the one I describe in chapter 2.3. The difference is that these patterns are much larger, the radius is 1-2 kilometers and the number of "petals" is approx. 500. These Viking graves look like a pyramid and consist of approx 100 000 tons of stone. The Viking graves have been centered on top of a curry cross and since the mass of the Viking grave is so much larger than the object I use in my experiment the pattern will be much larger. That is my theory. I know more than ten places in Sweden where similar interference patterns can be found. In one case the pattern has a diameter of 2.5 kilometers. The electromagnetic field is very strong at the centre of this large interference pattern, my L-rods respond violently. Trees that grow at this spot are severely damaged, on some trees the trunk is split in two or three parts, on others the trunk is heavily twisted; large parts of the trees are dead. In Sweden a few percent of the trees in a forest are damaged in the same way as I describe above (I guess the same is valid elsewhere). These trees "always" grow on a curry cross. The correlation is close to 100%.
6 Curry lines and our history
In Sweden almost all ancient monuments are placed on a curry cross. Graves from the Bronze age (500 BC), Viking graves (100-700 AD) and Runic stones (700-1200 AD) are "always" situated on a curry cross. I have noticed the same thing in Italy, the old Etruscan graves ( 500 BC) are placed on a curry cross and the houses and Temples of the Roman and Greek cities of Herculaneum, Pompeii and Pestum (close to Naples) are all placed so that their outer walls are in parallel and on top of the curry lines. In Sweden most farmhouses older than 100 years are build in the same way.
Conclusion: our ancestors where able to measure curry lines and the curry lines have not changed position during 2500 years.
7 Can we measure curry lines with electrical or magnetic instruments?
So far it has not been possible to measure the electromagnetic field from a curry line with electrical instruments. Why? The reason is that the curry line consists of a slowly varying static electromagnetic field; it is also a proportionately weak field. It varies so slowly that it can, in this respect, be considered as static. From a technological point of view it is difficult to design a device that detects a static field, it is also difficult to amplify the detected DC signal. The instrument will not be sensitive. It’s quite different with an alternating (AC) electromagnetic field; there we have technique that makes it possible to detect electromagnetic fields that are million of times weaker, ex. Radio signals from FM transmitters, mobile radios or signals from outer space.
However, the human being has developed an ability to detect electromagnetic fields and our ancestors have used this ability for thousand of years. We are not unique in this respect, many animals have this ability and they use it daily. The cat and the rabbit prefer to sleep in a curry cross. If you place your dog’s basket on a curry cross he will probably refuse to rest there. In Sweden ant-heaps are always build on a curry cross and the tracks leading to the ant-heap always following a curry line. This is valid for the "brown ant" that is very common in Scandinavia.
The human being has different senses, we can register pressure (static force), heat (high frequency electromagnetic field), light (photons) and sound (variations in air pressure). I venture to say that we have one more sense, the ability to feel static electromagnetic fields.
8 Conclusions
My first conclusion is that the field I measure from a curry line with a pendulum or L-rods is a static electromagnetic field. I have shown that a static electromagnetic field will create exactly the same phenomenon as the field from a curry line. I have shown that when I combine an electromagnetic field with a curry line I get exactly the same interference pattern as I get from two crossing curry lines or two crossing electromagnetic fields. I have shown that I can add an electromagnetic field to a curry line and depending of the phase the two fields will extinct or be amplified. I have shown that I can extinct the field from a curry line as well as an electromagnetic field with an electric short circuit. I have shown that the size of the interference pattern is proportional to the mass of the object irrespective if it is created by a curry cross or electromagnetic field from a crossing wire. I have shown that the field from a curry line generates a current in a conductor in the same way as an electromagnetic field does. In all these experiments the field from a curry line behaves exactly like an electromagnetic field and the two can be mixed in every possible combination. The probability that the two fields are identical is extremely high. Existing physical laws can’t explain the look of the interference patter but the rest of the results from these experiments are according to known physical laws.
My second conclusion is that the field from a curryline is a static electromagnetic field but it varies slowly; it changes its phase every 3.5 minutes (it has a period of 7 minutes). This is shown in chapter 3.4 and 3.5.
My third conclusion is that the field from curry lines is not generated by direct influence from the sun, the moon or the stars (as some people believe). The physical location of the curry lines have not changed during the last 2500 years and they do not change location during the day, month or year, see chapter 5 and 6. The earth moves in relation to the sun, moon and the stars, however this does not influence the position of the curry lines. I don’t exclude indirect influence from the sun.
My fourth conclusion is that the field, from two crossing curry lines influences trees that grow on a curry cross. The number of damaged trees close to the Viking grave Uppsa Kulle is striking; these trees grow on a curry cross. In Sweden you will see damaged trees everywhere, a very high proportion of these damaged trees grow on a curry cross. I have shown that when I place an object on a curry cross an interference pattern will occur. This interference pattern is an electromagnetic field created by the interaction of the two crossing electromagnetic fields and the molecules or atoms in the object. When a tree grows on a curry cross its cells are continuously, year after year exposed to a continuous disturbance. Sooner or later the cells will be damaged. A person that has his bed or workplace on top of a curry cross will be exposed to continuous radiation and the cells and tissue will be exposed to a continuous disturbance. If this exposure continues over many years the person can develop cancer.
9 Time and place of the measurements
I have repeated the same measurements at three different places and at three different times, outside the city of Nykoping (1997), outside Gnesta (2002) and in Stockholm (2002 & 2004). The results have each time been identical.
I have a master of science in electrical engineering and a 30-year career within telecommunications. It has been natural for me to capitalize on my professional experience in order to understand the phenomenon behind dowsing and curry lines.
