摘要：

An exact formula for the field produced by the eddy currents induced by transverse movements of a longitudinal planar domain wall in a magnetic cylinder is obtained. The result has been extended to satisfy the situation of bistable iron-rich amorphous wires and compared with the dM(av)/dt pulse of such wires during magnetization reversal. It is shown that the propagating wall is essentially planar and the damping is solely due to eddy currents.
