Magnetic and electrical characteristics of Supermalloy thin tape toroidal cores

This work presents the report on what the effect tape thickness has on the DC and AC coercivity, specific core loss, and dynamic B-H loop. The material used in this investigation is known in the trade as Supermalloy, which is a nickel-iron alloy whose chemical composition in percent mass is 79% Ni, 17% Fe, and 4% Mo. The Mo is added to increase the resistivity of the material and thus, reduce the eddy current loss. The Supermalloy tapes were wound on ceramic bobbins. The results of this investigations are finally presented.
