# permeability

Permeability is the permeability of materials to magnetic fields. Permeability is a dimensionless value that indicates the magnetic conductivity of materials. This value, given in the Greek letter "µ", tells by how much a magnetically conductive material is more conductive than vacuum. Vacuum forms the reference of permeability with a µ-value of "1".

This value is a constant and forms the absolute permeability in vacuum. Its value is µ0 and is calculated from 4pi*10^-7 (Vs/Am). The relative permeability
