Permeability — ParamagneticEasyQuestion 20185

Question

Relative permeability of a paramagnetic material is:
  1. A
    Much greater than 1
  2. B
    Slightly greater than 1
    Correct
  3. C
    Equal to 0
  4. D
    Slightly less than 1

Correct answer

Slightly greater than 1

Explanation

Paramagnetic materials are weakly attracted to magnetic fields; μr slightly > 1 (e.g., 1.00002 for O₂). Ferromagnetics have μr >> 1; diamagnetics have μr slightly < 1.
