Nerve excitation processes stimulated by trapezoidal magnetic fields

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 simulated, changing the rise-time, the duration of plateau and fall-time of the trapezoid. The results show that exciting point and threshold for nerve excitation change with the time course of the magnetic fields, even if stimulating intensity is at same level.
