I don’t know if this is common knowledge, but not all refrigerators nowadays are magnetic. When going out shopping for one, bringing a small fridge magnet can help you easily rule some models out if you care about that.

      Its how you shoplift cd’s. or at least it was back in the day. There is a metal band usually inside the CD or on the back of the CD which has a magnetic metal strip. Running a strong magnet against that strip was how they would disable the anti-theft device. YOU could achieve the same thing using a strong magnet.

      This didn’t work or tapes or VHS, because a magnet would destroy the content on the tape.
