Permittivity vs. Permeability

Permittivitynoun

(physics) A property of a dielectric medium that determines the forces that electric charges placed in the medium exert on each other.

Permittivity

In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (epsilon), is a measure of the electric polarizability of a dielectric. A material with high permittivity polarizes more in response to an applied electric field than a material with low permittivity, thereby storing more energy in the material.

Permeabilitynoun

the property of being permeable

Permeabilitynoun

the rate of flow of a fluid through a porous material

Permeabilitynoun

(geology) a measure of the ability of a rock to transmit fluids (such as oil or water)

Permeabilitynoun

(physics) a quantitative measure of the degree of magnetization of a material in the presence of an applied magnetic field (measured in newtons per ampere squared in SI units).

Permeabilitynoun

The quality or state of being permeable.

Permeabilitynoun

the property of something that can be pervaded by a liquid (as by osmosis or diffusion)
