<p>A device for applying a time-varying magentic field to a human or animal body for therapeutic purposes comprising a magnetic body (72) housed in a free moving member (80), which is itself housed within the device. The device is powered by a small electric motor that drives the free moving member (80) and magnetic body (72) to rotate about an exis of first rotation. The magnetic body is further caused to rotate around an axis of second rotation through angular forces imparted on it either mechanically or magnetically. Mechanical angular force is imparted by a gear and tooth arrangement or other similar tactile interaction with a roller member (106). Magnetic angular force is imparted by stationary magnets (110) as the magnetic body (72) rotates past them. The two rotational movements of the magnetic body (72) are oblique to one another and produce both a time-varying field of magnetic flux density and a time varying field of angular flux displacement.</p> |
