Permeance of a magnetic circuit
WebPermeance 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). Magnetic flux always forms a closed loop, as described by Maxwell's equations, but the path of the loop depends on the reluctance of the surrounding materials.

In a magnetic circuit, permeance is a measure of the quantity of magnetic fluxfor a number of current-turns. A magnetic circuitalmost acts as though the fluxis conducted, therefore permeance is larger for large cross-sections of a material and smaller for smaller cross section lengths. See more Permeance, in general, is the degree to which a material admits a flow of matter or energy. Permeance is usually represented by a curly capital P: $${\displaystyle {\mathcal {P}}}$$. See more Electromagnetism • Properties of Magnetic Materials (units of magnetic permeance) Material science • Bombaru, … See more In materials science, permeance is the degree to which a material transmits another substance. See more • Dielectric complex reluctance • Reluctance See more WebMagnetic permeability is defined as the ratio of the magnetic induction to the magnetic intensity. It is a scalar quantity and denoted by the symbol μ. Magnetic permeability helps us measure a material’s resistance to the magnetic field or measure of the degree to which magnetic field can penetrate through a material.
