Permeance

From Wikipedia, the free encyclopedia

Permeance, in general, is the degree to which a material admits a flow of matter or energy.

[edit] Electromagnetism

In Electromagnetic theory, permeance is the inverse of reluctance. Its SI derived unit is the henry (the same as the unit of inductance, although the two concepts are distinct).

[edit] Materials science

In Materials science, permeance is the degree to which a material transmits another substance.
