ABSTRACT:
A magnetic structure fabricated of magnetically rigid materials combines a adial magnetic field source with an axial magnetic field source to produce a conical field source. The radial magnetic field source typically comprises a substantially annular enclosed cavity with an internal magnetic field oriented perpendicular to the annular axis of the cavity. The axial magnetic field source most likely comprises a substantially cylindrical enclosed cavity with an internal magnetic field oriented parallel to the cylindrical axis of the cavity.
