As a student, I visited the High Field Laboratory in Dresden (Germany). They have one of the stongest magnets in the world, I think it was 80-100 Tesla, and supposedly stronger than a similar one in Los Alamos (although the one in Dresden could only be powered up once, and would vaporize immediately). The whole setup was surrounded by ~3m thick concrete walls.
And right next to the magnetic coil, behind a small blast shield, was an old PC... an early 90s beige box looking like a 486 or early pentium, controlling some measurement equipment.
We asked how that worked, and whether there are any problems with "EMP" with the hardware or the hard disk. The answer was, no, the PC works fine. But you have to be extremely careful not to leave any screws or screwdrivers around, because "above xxx T/m field gradient, iron starts to fly", as evidenced by lots of scratches on the concrete.
