Permittivity and Permeability
The resistance offer by the material in the formation of electric field
Permittivity
Permittivity is denoted by ɛ
The SI unit for permittivity is farad per meter (F/m)
Its physical basis is polaraization
The permittivity of free space is 8.85 F/m
It deals with the electric field and is used in Capacitor
Permeability
The permeability measures the ability of the material to allow the magnetic lines of force to pass through it.
Symbol is μ
In SI units, permeability is measured in henries per meter (H/m)
Magnetization
The permeability of the free space is 1.26 H/m
It deals with magnetic field and is used in inductor and transformer core
