Case in point an MRI machine.

Not 100% safe, at that.

I will give the "healing magnets" credit for one thing. The field strength at the surface of the cells at least exceeds those generated by high-voltage power lines, if not those generated by themal noise.

Indeed. That was a horrible accident. I was in an MRI for 45 min for a spinal exam. Very confining. I was very glad when it was over.
