Pulsed electromagnetic fields (PEMF) have been found to aid healing in some bone fractures, perhaps some types of wounds and to reduce certain types of pain for example. However they do not reduce pain in general or increase blood circulation etc as claimed by magnetic therapists. And they most certainly don't cure cancer.
Pulsed electromagnetic field therapy , also known as low field magnetic stimulation (LFMS) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression.[1] By 2007 the FDA had cleared several such stimulation devices.[2]
