WebSo, we arrive at our cryptic parallel equivalent resistance formula at last! Conductance (G) is seldom used as a practical measurement, so the formula above is common in the analysis of parallel circuits. Review of Conductance. Conductance is the measure of how easy it is for electric current to flow through something In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by William Thomson, 1st Baron Kelvin in 1872, and used alongside permittivity by Oliver Heaviside in 1885. The reciprocal of permeability is magnetic reluctivity.

WebReluctivity definition, the tendency of a magnetic circuit to conduct magnetic flux, equal to the reciprocal of the permeability of the circuit. See more. Webreluctivity or permeability. The conventional measurement of magnetic properties is based on the assumption that and BH are parallel and hence the magnetic reluctivity in the specified orientation is a scalar. The reluctivity in an arbitrary direction is then modeled by using that of the easy axis and its perpendicular direction [7].
