Abstract
Devices relying on the Inverse Wiedman Effect. Devices include a current conductive, magnetically anisotropic rod, through which an AC current flows. Wound about the rod is a conductive coil having output terminals. By varying the AC current, the anisotropy, or both, variations in the output across coil terminals can be obtained. Devices may be for current sensing, pressure sensing, fluid flow sensing or an electric push button.
Claims5
An electromagnetic device comprising a current conductive rod which exhibits magnetic anisotropy in other than a purely circular or longitudinal direction, a conductive coil wound about said rod, and means for applying an alternating current through said rod of sufficient magnitude to produce a helical magnetization of said rod in a given direction during one half-cycle of said current and for reversing the direction of said helical magnetization during the next half cycle of said current, whereby to produce a change in the linkage of axial flux in said rod with said conductive coil to cause an AC output signal at the terminal thereof.
