A.C. loss contributions of the transport current and transverse field caused by combined action in a multifilamentary wire [PDF]
, 1985 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.
