Permeability (electromagnetism) In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. It is the ratio of the magnetic induction to the magnetizing field as a function of the field in a material.Porous polymers are widely applied as adsorbents, ion exchangers, catalysts, and permeable materials.
