Uses of Ferromagnetic Materials

Uses of ferromagnetic materials (i) Permanent magnets The ideal material for making permanent magnets should possess high retentivity (residual magnetism) and high coercivity so that......

Describe on Hysteresis Loop in Magnetizing Field

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......

Describe on Hysteresis Loss

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......

Explain Properties of Ferromagnetic Substances

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......

Explain Properties of Paramagnetic Substances

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.......

Explain Properties of Diamagnetic Substances

Diamagnetic substances are those in which the net magnetic moment of atoms is zero. The susceptibility has a low negative value. (For example, for bismuth......

What is Magnetic Susceptibility?

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......

What is Intensity of Magnetization?

Intensity of magnetization represents the extent to which a material has been magnetized under the influence of magnetizing field H. Intensity of magnetization of a......

Define and Describe on Magnetic Permeability

Magnetic permeability is the ability of the material to allow the passage of magnetic lines of force through it. Relative permeability μr of a material......
