When you move a compass from the outside towards the inside and move it again towards the other outside of a coil you can see that the field changes directions. E.g. from North to South, from South to North, and again from North to South etc.
This is also the reason why you do not need to use a specific side of the PEMF coil applicator because the same field extends at both sides of the coil and the reason why you can use with the Curatron one ‘Very high energy coil’ for treatment of e.g. osteoarthritis in both knees at the same time by placing the coil between the knees.
In a compass the ‘South’ pole of the arrow points to the globe’s north but funny enough is called the ‘North’ pole! I hope I did not confuse you too much...
