Abstract: An apparatus and a method for treating ailments of the human body by electromagnetic waves. The body part to be treated is located inside an induction coil and the coil is energized by a switching device that supplies the coil with current pulses that include higher frequency components that occur during at least a portion of the pulse. Both manual and electronic switching devices are disclosed. The manual switching device uses manually operable striking contactors and the high frequency components are generated by arcing between the contactors. The automatic switching device is an electronic controller that simulates the current pulses produced using the manual method.

Abstract: An apparatus and a method for treating ailments of the human body by electromagnetic waves arm described. The body part to be treated is located inside an induction coil and the coil is energized from a storage battery through the special switching device. The switching device comprises a pair of metal rods one of which is hand-held by the operator and intermittently contacted with the other to apply successive pulses of current to the coil. The current pulses have a substantially rectangular waveform with a trailing edge produced by an arc discharge current when the switch is opened.
