Question

what are ferrities,application and it's future prospects.

Answer 1

Ferrites are materials made of Fe₂O₃ and barium, zinc, nickel, or manganese. They do not conduct electricity, although they can be used as permanent magnets: they keep the magnetization after the external magnetic field is removed. They are widely used in the cores of inductors, transformers, and electromagnets because such a material does not cause high eddy currents. The future prospects regarding ferrites: their nanoparticles can be considered as superparamagnetics.
