摘要： An apparatus for establishing at least one turn for a magnetic circuit includes: (a) at least one first magnetic element oriented substantially about an axis generally between a first axial position and a second axial position; and (b) at least one second magnetic element coupled with at least one selected first magnetic element of the at least one first magnetic element generally at the second axial position. The at least one second magnetic element establishes at least one return magnetic path from the second axial position generally toward the first axial position. The at least one return magnetic path is generally about the axis.

摘要： An electromagnetic apparatus having an adjusting effective core gap includes: (a) an electrical winding; and (b) a ferrous core situated proximal with the electrical winding. The core has a first terminus and a second terminus arranged in spaced relation to establish a gap distance between the termini in a region in substantial register with the termini. The winding and the core cooperate to establish an inductance related with an electrical current applied to the winding. At least one terminus of the termini has a configuration responsive to varying the current by effecting selective local saturation of successive portions of the at least one terminus for successive values of the current. The selective local saturation establishes successive new effective gap distances. Each respective new effective gap distance is appropriate for establishing a successive new optimum inductance for the current value then extant.
