minus-squarezr0@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up6·16 days agoAn MRI has a couple of Tesla, and everybody knows how dangerous ferromagnetic materials are close by. This new magnet here has 42 Tesla. I don’t even comprehend how you can turn this thing on without having forks and knives fly around 100m away.

minus-squareRedjard@reddthat.comlinkfedilinkarrow-up3·16 days agoWe have no magnetic monopoles, so at maximum this is a dipole field with inverse cube. Given they must be focusing in the field as much as possible, I’d expect it to drop off much faster than that.

Inverse square law my beloved
