A.C. loss contributions of the transport current and transverse field caused by combined action in a multifilamentary wire

A.c. losses caused by an a.c. transport current and a transverse a.c. magnetic field during simultaneous action were measured. The loss contributions have been obtained separately. The measurements were performed on a NbTi multifilamentary wire having a CuNi matrix of low conductivity in order to prevent eddy currents. The test configuration is presented and measurement results as well as theoretical confirmation are dealt with
