ABSTRACT:
A permanent magnet solenoid structure utilizes a hollow, tubular, toroidally-shaped flux source, an interior working space, a magnetizing member having an end magnet and two pole pieces. The magnetizing member intersects the flux source and the interior working space with the desired magnetic field being confined to the interior working space of the toroid by having a cladding magnet in contact with the outer surface of the toroidal supply magnet. In another embodiment, the interior working space is an annular ring rather than being toroidally-shaped. In yet another embodiment, the interior working space is an annular ring and an aperture or tunnel is provided through the magnetizing member so that electron particles can be electrostatically or thermally created, accelerated around the interior working space and then collected at a certain point within the interior working space.
