Magnetic Permeability vs Susceptibility
Magnetic permeability of a material is the ability of a material to support the formation of a magnetic field inside itself.
Magnetic susceptibility is the measure of magnetic properties of a material which indicates whether the material is attracted or repelled from an external magnetic field.
Units of Measurement
Magnetic permeability is measured by the SI unit Henries per meter (H/m or H�m−1) which is equivalent to Newtons per ampere squared (N�A−2).
The magnetic susceptibility is a dimensionless property.
Value for Diamagnetic Materials
The value of magnetic permeability for diamagnetic materials is less than 1.
The value of magnetic susceptibility for diamagnetic materials is less than zero.
Value for Paramagnetic Materials
The value of magnetic permeability for paramagnetic materials is greater than 1.
The value of magnetic susceptibility for paramagnetic materials is greater than zero.
Summary – Magnetic Permeability vs Susceptibility
Magnetic permeability is given by the units Henries per meter, and magnetic susceptibility is a dimensionless property of materials. The key difference between magnetic permeability and susceptibility is that magnetic permeability describes the ability of a material to support the formation of a magnetic field inside itself whereas susceptibility describes whether a material is attracted to a magnetic field or is repelled from it.
