Permeability of transformer core

WebPermeability really only makes sense for a uniform material. It tells you for a given magnetic field, H, what your magnetic flux density, B, is. In other words, B = μ H. So if you had a transformer with a core with no air gap and N turns of wire with current I in that wire and length l, your magnetic field will be H = N I l. An electric current through a wire wound into a coil creates a magnetic field through the center of the coil, due to Ampere's circuital law. Coils are widely used in electronic components such as electromagnets, inductors, transformers, electric motors and generators. A coil without a magnetic core is called an "air core" coil. Adding a piece of ferromagnetic or ferrimagnetic material in the cente…
