A magnetic medical treatment device and method wherein a coil received in a housing is energized with a periodic current of a predetermined frequency furnished from a power supply accommodated in the housing or disposed separately outside thereof to produce a corresponding, time-varying periodic magnetic field through the coil. A stylus formed of magnetically permeable material and electromagnetically associated with the coil means is positioned in engagement with a preselected surface zone of the body surface of an individual (patient) to selectively apply the magnetic flux to the surface zone.
