ABSTRACT

Ferromagnetic materials have the ability to carry high magnetic flux . Ferromagnetism refers to the property of increasing the magnetic flux associated with the material when a magnetizing force is applaid , but there exists a saturation point for most of the magnetic materials beyond which the associated magnetic flux does not increase . This condition is referred to as magnetic saturation . Ferromagnetic materials can be distinctly classified into two groups the magnetically soft and magnetically hard . The distinguishing properties are having high permeability and having easy to magnetize for soft materials and hard materials having high coercivity so that once magnetized the materials must be able to resist demagnetizing forces due to any appleid or stary magnetic fiels .
