PEMF Distance from coil

PEMF devices only able to generate low intensity fields

(in the micro Tesla range) require very sensitive electronic magnetic field detectors in order to show that some electromagnetic field is actually generated at all, because this field cannot be detected otherwise. These electromagnetic field strengths are unable to penetrate into the body more than an inch as becomes clear by the following explanation. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In the above picture visual light dispersion can be seen between the trees because the light is broken down because of the fog in the forest.

 

As result we see that the location where the light is "broken" the light intensity is the most concentrated. The further we go away the less light intensity and the more the light is spread out.

 

Exactly the same happens with electromagnetic energy.

 

 

 

 

 

 

 

 

 

 

Pulsed electromagnetic intensity decreases quickly with distance. If you move away from the source, the actual magnetic field intensity drops by the square of the distance. 

 

This means that if you have a specific field strength directly at the surface of the pad and you move away from the pad, the magnetic field strength drops fast. 

This becomes clear when we look at this picture.

 

All the energy passes through the lowest yellow area because it is close to the pad. When we double the distance away from the pad just 25% of the energy passes through a similar yellow area. Now double the distance again and see how little of the original energy passes through a similar yellow area at the top of the picture (around 11%).

This explains why it is crucial to have sufficient pulsed magnetic energy available from the beginning, otherwise it will do nothing deep inside the body, which is absolutely necessary for successful PEMF applications!

 

This is the reason why all PEMF devices must have electromagnetic field strengths in the high milli Tesla range in order to be able to penetrate the human body completely. Any device generating in the micro Tesla range will not have sufficient intensity further away from the coil pad.

 

This is not only what I believe in, but this is confirmed by numerous customers in more than 80 countries around the world, who altogether did millions of therapy sessions with PEMF devices manufactured by our company.

 

For the models controlled by external PC/laptop software the users can define the intensities for the field strengths themselves, even down into the micro Tesla range, in the rare case that they may want to use it exclusively for very superficial therapy purposes.   
 

In order to be able to accurately measure the Tesla values of pulsing electromagnetic fields, very special measuring equipment is required. 

 

 

 

 

 

 

 

 

 

 

 

Hall effect sensors are used, named after Edwin Hall, an American physicist, who invented the sensor. 

 

The use of a laser calibrated linear Hall effect sensor for this purpose is required in order to obtain reliable measurement values.

 

After amplification of the electrical voltage generated by the Hall sensor, the detected signals are visualized on an instrument called oscilloscope, which shows the exact pulse forms, and the Tesla values are obtained.
