What you were experiencing was a) probably real and b) due to the conductive properties of the ring , not magnetic. Oversimplification: Moving a conductor in a magnetic field or vice versa indices current in the conductor , resistance in the conductor results in heat. The main field in an MRI is static but there are a lot of other fields moving around… Similar happens on your body also (eddy currents) and deeper tissue gets energy which has to be controlled for - it can cause stimulation in peripheral nerves and heating . |
