Electrical Conductors: Definition, Types and Properties

An electrical conductor is a material that allows electric charge to flow through it with little resistance . Electrical conductors are usually metals, such as copper, silver, gold, aluminum, and iron. They have many free electrons that can move easily when an electric field is applied. Electrical c

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
