But yes, if you produce a strong EM field, you can heat up the metal that is near it.
Oddly, I sat in a big EM field this morning testing a generator core. I had to do a core loop test at one of the hydro generators. It's awesome to feel my old metal tooth fillings get warm. We have safety procedures to make sure we get anyone out of the area that has serious metal in their bodies away from the site while testing.
The whole point of the core loop test is to produce a magnetic field to heat up the stator core and find weakness by seeing hot spots in the heated metal of the core laminations.

I'm surprised OSHA, or your employer for that matter, allow you get be in a magnetic field of that strength. Not exactly good for the ol' body.
