Claim 16:
17. A method for degaussing a magnetized structure, the method comprising:
generating, at a first circuit, a alternating current (AC) signal that decays from an upper level to a lower level over a predetermined amount of time;
inducing, by a first electrical coil that is coupled to the first circuit and that circumscribes a magnetized structure, a decaying magnetic field on the magnetized structure in response to the AC signal to convert the magnetized structure into a degaussed structure; and
inducing, by a second electrical coil that is positioned in an interior portion of the magnetized structure, an offset magnetic field on the degaussed structure in response to the second electrical coil receiving a direct current (DC).
