[Inductive stimulation]

Electrical stimulation, which has long been known, has recently been complemented by electromagnetic stimulation. This method is based on the law of induction and employs coils in place of electrodes. The effect of this process is deduced from both the relationship between magnetic and electrical fields and the stimulating effect. A new type of stimulator has been developed from a resonant circuit, thus allowing nerves to be excited with low-frequency pulses up to fusion frequency.
