The electric potential energy of an electric dipole in an electrostatic field is the work done in rotating the dipole to the desired position in…

Like Charges, Repel and Unlike Charges Attract Each Other: Experimental Verification A charged glass rod is suspended by a silk thread, such that it swings…

The substances which acquire charges on rubbing are said to be ‘electrified’ or charged. These terms are derived from the Greek word electron, meaning amber.…

Ferromagnetic materials are usually used for nonvolatile information storage in tapes, hard drives, etc. They are used for two main technological applications: (i) as flux…

Consider an iron bar being magnetized slowly by a magnetizing field H whose strength can be changed. It is found that the magnetic induction B…

In the process of magnetization of a ferromagnetic substance through a cycle, there is expenditure of energy. The energy spent in magnetizing a specimen is…

Ferromagnetic substances are those in which each atom or molecule has a strong spontaneous net magnetic moment. These substances exhibit strong paramagnetic properties. The susceptibility…

Paramagnetic substances are those in which each atom or molecule has a net non-zero magnetic moment of its own. Susceptibility has a low positive value.…

Diamagnetic substances are those in which the net magnetic moment of atoms is zero. There are no atomic dipoles in diamagnetic materials because the resultant…

Magnetic susceptibility is the scale of magnetization of a substance in reaction to an functional magnetic field. Magnetic susceptibility (Xm) is a property which determines how…
