Abstract
A method for magnetically stimulating biological body to make treatment or diagnosis by applying a time-varying magnetic field to nerve, muscle or disease part, wherein alternate frequency, inductance, pulse width, peak value of current, and stimulation frequency are set appropriately for the disease part, and a litz wire coil is used to produce the time-varying magnetic field. Hence, the effective A.C. resistance with the skin effect can be reduced and the power consumption efficiency can be increased. Moreover, the heat generation of coil can be decreased. Also, a magnetically stimulating device uses acoustic insulation or noise absorbing material for reducing noise caused by contact between wound coil parts.
