I have a circuit that uses an electromagnet that is frequently energized and de-energized to various strengths. I am dealing with problems caused by remanence and need to degauss the EM from time to time. I was thinking to use a kind of flyback LC Topology, where I would switch in a cap when the EM is de-energized to induce AC ringing to degauss the EM. I was wondering if anyone had any experience with this kind of circuit design and if they were successful?
