Relative magnetic permeability

Relative magnetic permeability is defined as the ratio of permeability of medium (μ) to the permeability of free space (μ0) μr = μ/μ0 or                                 μr

Magnetic Intensity

Magnetic intensity is same as magnetizing force. Therefore, it is also defined as the degree to which a magnetic field can magnetise a material is

Magnetising Force

The degree to which a magnetic field can magnetise a material is expressed in terms of magnetizing force. Consider a toroidal solenoid with n turns
