I forgot to take my tungsten carbide wedding band off as well for an MRI, nor did the MRI techs say anything. It was in the middle of the MRI scan that I realized it was still on and then my fingers on the ring hand kind of started to feel fairly warm, but not certain it that was actually the ring picking up magnetic energy or if it was psychosomatic, but no harm became of it.

I looked it up afterwards and tungsten apparently as little to no magnetic effects, but depending on the amount of carbon used in it, it can.

Tungsten carbide jewelry is a mixture of tungsten carbide powder and a metal binder, typically cobalt or nickel. The metal binder is electrically conductive and thus susceptible to the induction heating you felt.

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 .

> little to no magnetic effects

Whether or not it’s a conductor is probably more of a concern. The loop likely wouldn’t be large enough to cause any drama though.
