    Unless he was using steel case rounds, most ammunition isn’t magnetic, it wasn’t going to cause issues with the machine… he’s still a fucking idiot though.

      An MRI works at 3T to 7T. At that range oxygen is slightly magnetic (Everything is magnetic, just not ferromagnetic). This can cause damage to the machine if it misaligned a critical component.

        Minor correction: the word for this is paramagnetic. Paramagnetism happens when a molecule has unpaired electrons, whereas diamagnetism happens when a molecule has no unpaired electrons. You’re pretty much entirely right, though

        That’s fair, I miss read that, assumed he had dumped a mag full of rounds on the ground, vs a mag with rounds in it.
