### Why do paramagnetic materials have constant permeability?

Paramagnetic materials have a constant relative permeability slightly greater than 1, thats why when a paramagnetic material placed in an external field it gets feebly magnetized in the direction of the magnetic field.See all results for this questionWhat is the permeability of a material?The permeability of a material, therefore, is a measure of the ease with which magnetic flux lines can be established in the material. It is similar in many respects to conductivity in electric circuits.

### What is magnetic permeability?

Magnetic permeability also referred to as just permeability in electromagnetism is a property of a magnetic material which supports the formation of a magnetic field. The term was coined by Oliver Heaviside in the year 1885.
