3. Ferromagnetic circuits. Ferromagnetic materials

3.1 Characterization

All materials have a permeability very close to or equal to that of a vacuum, with the exception of ferromagnetic materials. These consist of iron, nickel, cobalt and their alloys. They are characterized by a permeability μ f significantly higher than that of vacuum:

μf≫μ0

Relative permeability μ rf = μ f / μ 0 varies from 10 to 10,000, depending...
