This steady field, 35.1 T, is considerably lower than the record, 48.7 T, established at the National High Magnetic Field laboratory in Florida. That magnet used a combination of superconducting and normal conductor coils.

Was just going to mention the MagLab, which all the locals think controls the weather and keep hurricanes away, so much so they have to say it does not in the FAQ:

Interesting, I did not know that. Thanks for sharing!

Just for comparison, you can buy a 28 Tesla magnet that is stable over long times. Well, it's part of a 1.2 GHz NMR spectrometer, but I suspect it's the strongest magnet of that kind you can buy off the shelf.

These comparisons are often not quite fair and compare different things. The conversion to press releases tends to remove all nuance beyond "strong magnet".

There is an Veritasium video where they visit that lab.

The difference here, which is almost lost in the article, is that ASIPP's is a fully superconducting magnet, unlike the Little Big Coil.

What level of "can buy" are we talking about here? You got a part number?

It’s practically on fire sale at Digi-Key.
