ABSTRACT:
An electromagnet having a conical bore. The conical bore is created by wrapping a conductor around a conically-offset helix. The cross sectional area of the conductor can be varied in order to maintain a desired current carrying capacity along the helix. A single element can be used as the conductor. The conductor can also be created by stacking a series of specially-shaped plates analogous to prior art Bitter-disks.
