The First Room-Temperature Ambient-Pressure Superconductor

MRI will get much cheaper, but you still need a good upper critical field and a proper access control (Zone 2/3/4) protocol. So probably not in very small buildings.

From what I can tell this material can't provide higher than 0.3T. We've had permanent magnet MRI at 0.3T but the drawbacks vs superconducting magnets are weight and lack of active shielding.

With room temperature superconductivity doesn't it become possible to turn the magnet on and off far more easily? MRIs would be much safer if they were only energized during the actual imaging process.

To turn the magnet off you need to get the current out, I don't see why raising the temperature would make that easy.

Dump it in a bank of capacitors, send it back when you need it. Or in a superconducting loop...

How does the temperature come into play?
