Where: ΦB = Magnetic flux NI = Current-turns, (current) × (number of turns of conductor to make a coil). Where: μ = Permeability of material The SI unit of magnetic permeance is `webers per ampere-turn`, that is Wb A-1. ==Materials science== In Materials science, permeance is the degree to which a material transmits another substance. ==Exter.....
