Homework Help: Vacuum chambers and magnets

  1. Jul 27, 2011 #1
    Do magnets have a longer reach of attraction in a vacuum chamber?

    All else being equal, I don't think the attraction force would be significantly different in a vaccum than in air, because the magnetic permability of air is only slightly greater than the permability of a vacuum.

    The permeability of the vacuum of free space is practically identical with that for air. So, no, the field around a magnet remains the same shape and strength.
