Abstract
A series of parallel spaced conductors through which currents are sequentially switched. A spatial relationship of the sequentially switched currents is chosen such that, at different times, tangential and normal magnetic fields are produced at the same location. The conductors are preferably arranged in a planar fashion and the tangential and normal magnetic fields are produced above the planar surface. A single layer of parallel spaced conductors provides substantially two dimensional operations. Adding a second parallel layer of orthogonally oriented parallel spaced conductors provides substantially three dimensional operations where currents are sequentially switched in both layers.

24. A method of energizing a first arrangement of coils and a second arrangement of coils, the first coils having a at least two first windings and the second coil having at least a second windings, the second winding being juxtaposed intermediate the first windings, the method comprising the steps of:
