what  are permeability and permittivitty?

anonymous · Answer

Permeability is a material's natural ability to sustain a magnetic field.
Permittivity is a materials' resistance to the formation magnetic fields.

Permeability is a material's natural ability to sustain a magnetic field.
Permittivity is the measure of the resistance that is encountered when forming an electric field in a medium

anonymous · Answer

abhinayreddy is right, The permittivity relates to electric fields, not magnetic fields. 

Permittivity is represented by epsilon while Permeability is represented by mu, Think $$\epsilon - lectric <-> \mu -agnetic$$
