An apparatus and a method for treating ailments of the human body by electromagnetic waves are 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.
