The term Absolute Permeability (๐โ) of a material is the product of permeability of free space ๐₀ ( = 4๐ ⨯ 10⁻⁷ henry/meter) and the Relative Permeability ๐แตฃ .
i.e.
Relative Permeability (๐แตฃ) of a medium is defined as the force between two poles when placed at a fixed distance in vacuum to the force between them at the same distance in that medium.
The Relative Permeability is a pure numerical number and therefore has no units. As mentioned above, for air and non-magnetic materials, its value is unity.
