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. https://nationalmaglab.org/news-events/news/a-prototype-mini...

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: https://nationalmaglab.org/about-the-maglab/facts-figures/ma...

Quite funny faq to read

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.
