| Abstract: | This article introduces a magnetic field generating device, of which the parameter is adjustable.This system includes oscilla-tor, second-order system, counter, decoder,circuit and Helmholtz coils etc., and is primarily used for the research of biological ef-fects.This article expounds how to control the magnetic intensity and frequency generated by Helmholtz coils through adjusting the pa-rameters of the second-order system. The frequency of the device ranges from 1 to 325 KHZ, and the magnetic intensity is no more than 200Gs, and the actual deviation from the theoretical value should be within 15%. |
