    He said he would drop the glass on the magnets, not put them underwater. You can demagnetize a permanent magnet by violently striking it in the absence of a background field.

    I’m not saying he’s good, but I don’t think he’s entirely wrong.

    Don’t know why they didn’t use John Deere though.

      The magnitude of physical stress waves a magnet has to undergo to be demagnetized is huge. Most magnetic materials will shatter instead unless the force is applied precisely.

      I think he vaguely remembered something about electromagnetism and that water on electronics is a no-no.

      The main takeaway is that he should appoint an engineer to advise him on technical topics (and Surgeon General on medical matters, etc.), otherwise any sufficiently sly corporate sponsor or media can easily steer his policy by pretending to be experts. I guess the only fields he does not need to delegate are being a douchebag on TV and lying about real estate.

        Citation needed! I’ve done it with a cheap iron magnet and a hammer.

        Anyway I think he implied that these magnet was just below Curie temperature.

        He might just be a stable genius.

            Now we’re talking science!

            I’ll write the funding proposal at once.

          Iron magnets are crap, but I imagine he does not know better having gone to school in the 50s-60s. But yes, those are magnetically weak enough and physically strong enough for a hammer to work.
