Chinese scientists set world record with magnetic field 700k times Earth's (opens in new tab)

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.

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".

It's remarkable that it's so hard to create high magnetic fields. 35 T is only 35 times higher than what's in a regular loudspeaker or brushless motor. The electric field possible in a lab must be much more than 35x what's in consumer devices.
