Permalloy, Perminvar and Mumetal Permalloy : It is a soft magnetic material, it is an alloy of Iron and Nickel.( Iron=78.5% and Ni = 21% ), which can be magnetized by a very weak...

Magnetostriction : When ferromagnetic materials are magnetized, there are small changes in its dimensions. The phenomenon is called Magnetostriction. When subjected to rapidly alternating magnetic fields there is a rapid and continuus  extention and...

Curie Point / Curie Temperature There is a critical Temperature called Curie Point, above which the ferro magnetic material lose their magnetic property and to become a paramagnetic material. The curie temperature is named...
