This was interesting. https://www.youtube.com/watch?v=sDE2uekqLsA After I watched it I realized that if he is correct, the simple way to test would be to put a compass next to the transformer with the AC disconnected. If the needle deflects that would indicate that the core of the transformer has been magnetized by DC. ray |

With AC going through the transformer then the magnet could never form |
