Fluid that is a permanent magnet at room temperature?

  1. Apr 3, 2015 #1
    Hi
    Is there any fluid that is a permanent magnet at room temperature? (Ferrofluids do not retain their magnetic effect hence temporary).
    Thanks

    HI I couldn't imagine or know of any fluid that could be a permanent magnet at any temperature
    The continuous random orientation of the magnet moments of the particles in a fluid would negate
    the possibility of an orderly magnetic field being formed
