Classification: CPC H | IPC H

Claim 0:
1. A system for degaussing a magnetized structure, the system comprising:
a first circuit that provides an alternating current (AC) signal that decays from an upper level to a lower level over a predetermined amount of time;
a first electrical coil coupled to the first circuit, wherein the first electrical coil circumscribes the magnetized structure, wherein the first electrical coil induces a decaying magnetic field on the magnetized structure in response to the AC signal to convert the magnetized structure into a degaussed structure; and
a second electrical coil that is positioned in an interior portion of the magnetized structure, wherein a direct current (DC) signal is provided to the second electrical coil to induce an offset magnetic field on the degaussed structure.
