Introduction to Electrical Engineering [ELL100]
web.iitd.ac.inINTRODUCTION 2 A magnetic circuit is made up of one or more closed loop paths containing a magnetic flux ϕ (= magnetic field/flux density B × cross-sectional area A). The flux is usually generated by permanent magnets or electromagnets and confined to a path by magnetic cores consisting of ferromagnetic materials like iron, although there may be air gaps or other …
