An increment in inductance per unit density of the magnetic complex layer disposed above or below the receiving coil is 25%.Math.cm.sup.3/g or more compared to an increment in inductance per unit density of the magnetic complex layer alone not disposed above or below the receiving coil.

A system and method for perturbing a permanent magnet asymmetric field to move a body includes a rotating body configured to rotate about a rotation axis, a permanent magnet arrangement arranged on the rotating body containing two or more permanent magnets, and a perturbation element. The permanent magnet arrangement is configured such that an asymmetric magnetic field is generated by the permanent magnets about a perturbation point. Actuation of the perturbation element at or near the perturbation point causes a tangential magnetic force on the rotating body and/or the permanent magnet arrangement, thereby causing the rotating body to rotate about the rotation axis. The disclosure may also be used for linear motion of a body.
