Electromagnetic Field Polarity of PEMF
It makes no sense to claim that PEMF pulsed electromagnetic fields have a positive and/or negative field. This is also the situation for statments that there is a North or South pole magnetic field for pulsed electromagnetic fields because the pulsed fields change polarity the whole time.
When you take a compass and move it from the outside to the inside of a PEMF coil or if you move it towards the outside of the coil, you can clearly see that the field direction changes. E.g. from South to North and from North to South and again the other way around etc.
This explains that you do not need to use a specific side of the PEMF applicator because an identical field extends at both sides of the applicator. When using the Parmeds PEMF system both sides of one ‘Very high energy coil’ can be used for therapy e.g. treatment for osteoarthritis in both knees by placing the coil between both the knees.
Only static magnets do have a South and North pole, alternatively called positive or negative by static magnet sellers.
By the way do you know what side is called the ‘North pole’? The side attracted to the real North Pole or the side attracted to the South Pole? Interesting right? Usually sellers of magnets have no clue of what they are marketing!
In a compass the ‘North’ pole of the arrow points to the globe’s south but interestingly enough it is called the ‘South’ pole! We trust you are not too confused now...?
