The magnetic field itself (at least in current machines) is not capable of burning the patient. TVMF (Time-varying magnetic field) MRI can cause eddy currents, but these are very small, and the primary danger from these is shocks and siezures, not burns. If the patient has electrically-conductive items in their body (implants, etc.) the magnetic field can also cause harm in that way, but this is usually not a problem since patients are screened for these types of implants beforehand.
TIL. My applied friends in the area are mostly working with lab animals, so maybe they just weren’t cautious enough with their own metallic items? Who knows.
