Why MRI Pulls Metal Even When Off

HOSPITAL MRI magnets NEVER turn off. 24 hours a day. 365 days a year. 🧲 Even when the machine is off. Because the magnet keeps running on its own. Why?👇 Inside a hospital mri machine is a super-cold coil where electricity keeps flowing by itself. So a mri magnet stays on even during a power cut. Turning off the machine does not turn off the magnetic field around it. That's how mri works — and why metal is never allowed near an MRI room. Only a trained engineer can shut it down, or an emergency mri quench button, which costs $30,000+.
