The invention relates to a device for generating a very-low-frequency pulsed magnetic field carried by a very-low-frequency alternating magnetic field and intended to be applied to a region of the human body, the device is provided with a plurality of pairs of angular magnet sectors of opposite polarity, the pairs of angular magnet sectors being centered on one same axis of rotation, angularly spaced apart from one another, and set in rotation at a predetermined speed about the axis of rotation so as to generate an alternating magnetic field at a predefined frequency, and at least one conductive wire coil centered on the axis of rotation of the angular magnet sectors and supplied with a pulsed electric current so as to generate a pulsed magnetic field superimposed over the alternating magnetic field generated by the setting in rotation of the angular magnet sectors.

It is well understood in the medical industry that medical disorders can manifest as serious problems for the affected subjects, their families, and society. Today, psychiatrists, neurologists and other physicians treat these disorders with a variety of medications, many of which have significant negative side effects. The teachings provided herein are directed to a novel system and methods for treating certain neurological, psychological, psychiatric and medical disorders by delivering a “magnetic stimulation” to a subject's neural and perineural system using either a static or electromagnetic field to generate a modulated variable power multi-spectral magnetic stimulation on three axis; the modulated stimulation using methods that have predictable, controlled, modifiable, and repeatable characteristics.
