The magnetic permeability µ characterises the permeability or magnetic conductivity of materials. It is the product of the magnetic field strength µ0 und the relative permeability µr, which we can determine for paramagnetic materials (µr = 1...2).
The relative permeability of vacuum is 1.
Materials can be classified into 3 groups with regard to their relative permeability:

  • Diamagnetic materials     0 ≤ µr 
  • Paramagnetic materials     µr > 1
  • Ferromagnetic materials     µr >> 1
