Answer:
Magnetic permeability is defined as the ratio of the magnetic induction to the magnetic intensity. It is a scalar quantity and denoted by the symbol μ. Magnetic permeability helps us measure a material's resistance to the magnetic field or measure of the degree to which magnetic field can penetrate through a material.

Answer :
Magnetic permeability is the relative increase or decrease in the resultant magnetic field inside a material compared with the magnetizing field in which the given material is located.
UNIT : henries per metre (h/m) in Si system.
Magnetic susceptibility is the degree to which a material can be magnetized in an external magnetic field.
UNIT : it is dimensionless.
