Hard Magnetic Materials

For understanding the hard magnetic materials , we have to know certain terms. They are as follows: Coercivity: The capability of a ferromagnetic material to hold up (resist) a peripheral magnetic field without getting demagnetized. Retentivity (Br): It is the amount of magnetism that a ferromagneti

Ferroelectric Materials: What Are They?

What are Ferroelectric Materials? Ferroelectric materials are materials that exhibit Ferroelectricity. Ferroelectricity is the ability of the material to have a spontaneous electric polarization. This polarization can be reversed by the application of an external electric field in the opposite direc

Soft Magnetic Materials

First of all we need to keep certain points in mind before defining the soft magnetic materials . Remanent Induction: It is actually the value of induction which residue, once the material is magnetized and then the magnetizing field is decreased to zero. It is denoted by B r . Coercive Force: It is
