The last thing I need is a Wang magnet on the fridge.
If this works and doesn’t have some unknown limitation (temperature, etc) this is amazing because it doesn’t use rare earths like neodymium (which are, not surprisingly, “rare”). I’ve read articles that supplies of rare earths might limit the growth of electric cars in the future. BTW, every hard disk made in at least the last 10 years contains one or two neodymium-based magnets.
I knew a chick in high school that was a regular wang magnet.
