Mu-metal was made by Coballoy - don't know if they're still in bid'niss.
You may have a bit of a problem though, 60 Hz is tough to stop and
mu-metal was not cheap.  My rotor boxes do the same thing when the brake
is on.  It only took a couple of inches separation to make the effect
quite tolerable, but not on a continuous basis.
