Magnetolytic corrosion


I was opening up one of my alternators today and noticing that the fasteners on the case are in not so good shape; and under the paint, the case isn’t pristine, either. I’m wondering, can its magnetic fields be the reason? maybe. Electric current can cause or prevent corrosion, is it crazy to think that magnetic fields could do the same? And is this a design consideration for things that are meant to be in strong magnetic fields?


I don’t really think so. The mechanisms referenced in the paper only apply to electrochemical reactions in a liquid. Incompatible metals seems a much more likely explanation…
