<p>the flux field and controls unwanted stray induction currents as well as stray flux from the opposite pole. A flux focusing ring (16) is positioned around the flux heads adjacent to the insulated wire coils. Attachment means hold the focusing ring in proper location for maximum benefit. Attached to the flux focusing ring are focusing coils (18a, 20a, 22a, and 24a). These focusing coils are attached to the flux focusing ring in proximity to a head of like charge and at 45° to 90° angle to the long axis of the primary flux pole. In this position, the flux focusing coils along with the focusing ring, the flux return ring and the new iron core of this invention make the gradient steeper, increase the field strength and decrease heating and stray high currents. The flux return ring and the flux focusing ring are grounded to reduce stray iThis invention is a magnetic treatment device for therapeutic application to the human body, and more particularly an electromagnetic quadri-polar treatment device (12) with a focusing ring (16) to increase the intensity, focus and gradient of the field for placement against or in proximity to the human body.</p> |
