Abstract

Magnetic nerve stimulators activate nervous systems by inducing electric fields inside the tissue. It has proved to be an effective noninvasive technique that can be used to excite peripheral and central nervous systems. In this technique, the excitement of the neural tissue depends on exposing the body to a transient magnetic field. This field can be generated through passing a high pulse of current through a coil over in a short period of time. The general guidelines for designing and constructing a Function Magnetic Stimulator (FMS) were described. RLC model that produces the impulses in FMS was presented. Some factors that influence induced magnetic field were discussed. Experiments were carried through with self-developed round coil and 8-shaped, and Tesla meter was used to detect the magnetic fields. The experimental data show that the distribution of the induced magnetic fields by the two coils is tailored to those of theoretical calculation adopted now.
