ABSTRACT:
A magnetic field generating device comprising a frame about which a current carrying coil of conductor is wound. The frame preferably includes spaced-apart side panels and an auxiliary supplementary cooling system panel. Each of the panels is configured with a plurality of spacers and/or perforations to facilitate and encourage the movement of air within the apparatus. The spacers are preferably provided on the interior surfaces of the primary panels to maintain the coil winding in a centered position therewith. Spacers may also be interpositioned between the various layers of the coil itself to enable airflow into and around the various coil layers. Of course, in the alternate embodiment a plurality of coils may be provided such that each individual layers or combination thereof may comprise an individual coil. The preferred frame includes a perforated panel, a substantially non-perforated panel, and a auxiliary supplementary cooling system panel to enable the airflow from within the air space itself interpositioned between the perforated panel and substantially non-perforated panel into the air space established by the auxiliary supplementary cooling system panel and the perforated panel prior to exit and expulsion to the outer atmosphere.
