PEMF stands for Pulsed ElectroMagnetic Field. PEMF Therapy is the use of Pulsed Electromagnetic Fields for the treatment of a wide variety of ailments ranging from healing broken bones to depression.
A PEMF therapy device induces microelectric currents into damaged tissues by way of the induction effects of changing magnetic fields on a conductor.
This is basically the way transformers and generators work. a varying magnetic field in the presence of a coil of wire induces a current to flow in the coil of wire. The stronger the magnetic field, and the biigger the coil of wire, the more the current flow.
In PEMF therapy, the conductors are the cells of the body. They aren’t coils of wire, so the induced current is very small. However, this small electric current is enough to reduce swelling, which then promotes natural healing to take place.
