Ferromagnetic materials can be simply stated as the substances which are strongly attracted by a magnet. These have an ability to regain its property in the absence of magnetic field. lines of forces due to the applied magnetic field are strongly attracted towards the material. Above curie’s temperature all ferro magnetic materials become paramagnetic. Ferromagnetic materials may exist as conductors, insulators or as semiconductors. There are wide applications available such as it can be used in devices such as electric motors, debit In these the magnetic card, magnetic tapes, generators, telephones.
