Most plastics, wood, non ferrous metals, air and other fluids have permeabilities very much lower: 0. Materials with high permeabilities include iron and the other ferromagnetic materials. Permeability as representing 'conductivity for magnetic flux' just as those materials with high electrical conductivity let electric current through easily so materials with high permeabilities allow magnetic flux through more easily than others. magnesium, molybdenum, lithium, and tantalum These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Diamagnetic materials have a weak, negative susceptibility to magnetic fields, copper, silver, and gold.Paramagnetic materials have a small, positive susceptibility to magnetic fields. The 'curves' here are all straight lines and have magnetic field strength as the horizontal axis and the magnetic flux density as the vertical axis. Core materials with a higher permeability than air increase the magnetic field and confine it closely to the inductor, thereby increasing the inductance.
