Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. It is the degree of magnetization that a material obtains in response to an applied magnetic field.
It is a constant of proportionality that exists between magnetic flux density and magnetic field intensity.
B = μH
The units of magnetic permeability are henry per meter
As the flux density (B) is proportional to the flux intensity (H), it increases, when flux intensity increases.
Additional Information
The Total magnetic flux per unit area is called magnetic flux density.
It is given as B = \(ϕ\over A.\)
Where "B" is the magnetic flux density
ϕ is the magnetic flux unit Wb
A is the total area in m2
The unit of flux density is weber per m2. The SI unit is Tesla.
