One thing that goes unmentioned about room temperature superconductors is that they store energy as well. U = (B2/(2u0))V. 2u0 is about 2.5E-6N/A2 So a 1m3 7T

So a 1m3 7T magnetic field would be about 20MJ or 7KWh. That doesn't sound like much, but collapse times could be microsec to generate GW of EM.
- xbar 2y agoThis is a useful fact to have handy.
- justlikereddit 2y agoCommercial MRI quenching doesn't result in explosions and there's 7T research MRIs so I assume the issue with how to bleed off energy is solved in a safe enough manner already
- gaze 2y agoThese novel new superconductors are generally considered to be "bad superconductors." They have really low critical fields.
