I work on software for MRI machines, and one of the first things they do is high powered magnet safety training which is mandatory for everybody.

Even non-ferromagnetic materials react to the high field strength, and to show that, they let me hold a ring of aluminum just outside the bore. You can feel it "snap" to either parallel or perpendicular to the table when you try to turn it. It was a surreal experience.
