Switching the signal polarity consecutively from South to North and vice versa, is a very important feature of any state-of-the-art PEMF system. Our organism tends to acclimate or habituate to external, simplistic information and gets literally “used to it” or “tiresome” (i.e. static magnets or simple PEMF sine wave forms). As a result, over time, PEMF benefits may diminish and the application becomes less sustainable. Polarity changes in a PEMF device differ slightly from the South and North polarity of a static magnet. You will NOT find magnets in PEMF applicators, rather and ideally pure copper current loops, genera-ting pulsed electromagnetic fields with a high variation in frequency. Therefore, switching polarity occurs once the current in the loop is changing direction. This added signal variety prevents the body’s fatigue to the same wave form.
