This paper studies a pulsed magnetic-field generator which provides a noncontact way for functional nerve stimulation. Each component of the device, such as charging circuit, discharging circuit, and control circuit, is described in detail. The feasibility of the device is verified by simulation and experiments. The magnetic field and the induced electric field are produced by a figure-8 coil under excitation of pulsed discharging current. According to the Schwarz model, the action potentials of nerve fiber are simulated, and the neural dynamic response is predicted.
