Magnetic iron = 200
The magnetic constant μ0 = 4π x 10-7 T m/A is called the permeability of space. The permeabilities of most materials are very close to μ0 since most materials will be classified as either paramagnetic or diamagnetic. But in ferromagnetic materials the permeability may be very large and it is convenient to characterize the materials by a relative permeability.

Iron is not permeable. Iron has a lattice structure which does not permit the flow of fluids through it. Permeability refers to membranes, like colloidal membranes used in dialysis. I think perhaps you mean the soluability of iron in a particular solution?

it changes with temperature, as you might expect, but for high purity Iron, at 0 degrees C the permeability is 920 (gauss/oersted)

probably, somewhere.
