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.
I think the key point is they did it with a superconductor. My understanding is that while superconductors have zero resistance, there's still a limit to how much power you can dump into them before superconductivity breaks down.
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:

What level of "can buy" are we talking about here? You got a part number?
It’s practically on fire sale at Digi-Key.

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

Quite funny faq to read
Interesting, I did not know that. Thanks for sharing!
There is an Veritasium video where they visit that lab.
