Palm-sized magnet reaches 42 tesla, approaching the strength of the world’s most powerful magnets while using a few thousand times less power and over 1,000 times smaller coil volumes (interestingengineering.com)

Inverse square law my beloved

And Tesla is probably a linear scale. Then what are they excited about mere 42 Tesla. We need 40 kilotesla next.

We 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.

See I started with inverse cube and then edited it because I'm a coward
