Abstract :
This study focuses on the properties of nerve excitation elicited by time-varying magnetic fields. We analyzed the effects of trapezoidal magnetic fields on the nerve transmembrane potential. Nerve excitation processes were stimulated while changing the rise time, the duration of the plateau, and the falling time of the trapezoidal signal. The results show that the exciting point and the threshold for nerve excitation change with the temporal behavior of the magnetic field, even when the stimulating intensity remains the same.
