Effect of external magnetic field on characteristics of current-carrying steel tape
Abstract
The behavior of a current-carrying tape of steel or other ferromagnetic material in an external magnetic field is analyzed, specifically for the case where the magnetic-induction vector is tangent to the tape surface and normal to the current-density vector. Interaction of the external magnetic field and the intrinsic magnetic field within the tape volume, the former a uniform one and the latter a nonuniform one, is treated as a superposition of such fields in a nonlinear medium. A mathematical model is constructed for constant magnetic fields and a rectangular strip of width 2h and thickness 2d. Calculations are based on the fundamental law of magnetic circuits.
