A PEMF system makes its magnetic field with a coil of wire and an electric current that is switched on and off in a set pattern. The coil turns the current into a field, and the switching makes that field pulse. If you are weighing up a system, start with what the equipment itself does.
PEMF stands for pulsed electromagnetic field
An electromagnetic field is the field an electric current produces. Pulsed means the field is not held steady. It rises and falls, over and over, in a pattern the system sets.
A coil turns current into a magnetic field
When an electric current passes through a coil of wire, a magnetic field forms around the coil. Stop the current and the field falls away. This is ordinary physics.
Switching the current on and off makes the field pulse
The system’s electronics switch the current on and off. Each time the current starts, the field builds. Each time it stops, the field drops. Repeat that in a regular pattern and you have a pulsed field.
The coils sit inside the mat or applicator
A PEMF system builds its coils into a mat or an applicator. The electronics send current through them in the pattern the system sets, and that is how the system makes its field.
