    MRIs are entirely electrical right? They just use liquid helium for cooling im pretty sure.

    Obviously there are a bunch of mechanical parts as well, that goes without saying i think though. Most people wouldn’t be able to tell you the difference between mechanical logic and solid state logic anyway.

      Yes, you are right, but I meant the safety shutoff mechanism. Normally it just cuts the power to all dangerous stuff or brings it to a safe state. Here it’s not “cutting the power to the magnet”, it’s physically releasing the helium and damaging the superconductor in the process.

        yeah, sometimes that’s normal though. In the case of a giant magnet that will literally rip you to shreds if you have a piece of metal in you, that’s probably a reasonable emergency stop procedure.

        Unless there’s a second less aggressive emergency stop button that just cuts off the power, in which case this is just a huge fucking shitpost from that police officer
