Distinguish between absolute permeability and relative permeability of a medium
1. Absolute permeability is the ability of the medium to allow the magnetic lines of force to pass through it, or to allow it self to be influenced by magnetic field.
2. Denoted by μ
3. has the unit henry/metre
1.The relative permeability is the ratio of the permeability of a medium to the permeability of free space.
2.Denoted by μr
3. has no units
