The human body is a good conducting medium and that also applies to magnetic fields. As ions in a cell have a charge, the cell membrane also needs a certain amount of charge.

The membrane charge of normal, healthy cells is higher than that of diseased or aged cells, including bacteria and viruses. When the cell membrane charge is low, the cell has too little energy to perform its normal function.

Therefore cells need energy, and stimulation via an electro-magnetic field is known to increase this energy and optimize the function of the cell.

Electromagnetic fields can penetrate cells, tissues, organs and bones without any change or loss, activate the electrochemistry of tissues, and improve cell and cell membrane function. 

The emFieldPro generates a magnetic field of up to 3 Tesla, which is about 600 times stronger than a normal magnet. This strong magnetic field then stimulates nerve cells, muscles, and blood vessels.
