    I was talking to my husband who has been traveling for work to an industrial site, and he sent me a picture that included a “permanent magnetic lifter”.

    They look like this: https://www.magnet-sdm.com/wp-content/uploads/Permanent-magnetic-lifter.jpg

    I had never heard of these and wondered how they worked - how is it possible to “turn off” a magnet without electricity??

    I found a video where someone explains how this is possible: https://www.youtube.com/watch?v=PMma3OJUHhs

    I got one of the smallest of these as a gift for my husband. This tiny thing is strong enough to lift 68kg. It’s strong enough to lift me!

      This is an ingenious use of magnets! Thank you for sharing. I feel like I know something the general public doesn’t know, making me feel oddly powerful. hahaha

      Neat. I use small versions of those at my job all the time. I’ve always wondered how those worked.
