WebMost plastics, wood, non ferrous metals, air and other fluids have permeabilities very much lower: μ 0. Just as electrical conductivity is defined as the ratio of the current density to the electric field strength, so the magnetic permeability, μ, of a particular material is defined as the ratio of flux density to magnetic field strength - WebA material's permittivity and its conductivity are fundamentally different quantities, and cannot generally be calculated from one another, particularly if all you have are static measurements. The main reason for this is that a material's permittivity is a purely static property, while its conductivity involves its dynamics.
