good morning

Answer 2

PERMEABILITY is the measure of resistance of a material against the formation of the MAGNETIC FIELD .

.) Generally a FERROMAGNETIC MATERIAL doesnt have a constant permeability .

.) Permeability of a ferromagnetic material increases with the increase of the magnetic field under which our ferromagnetic substance is present .

.) Generally permeability can be express as :

B = αH

Where B is the magnetic field , α is the permeability and H is the MAGNETIC INTENSITY.
