Phenomena of hysteresis and its applications
What is Hysteresis? Hysteresis occurs in a system that involves a magnetic field. Hysteresis is the common property of ferromagnetic substances. Generally, when the magnetization of ferromagnetic materials lags behind…
Dia, Para and Ferro magnetism
What is Magnetic susceptibility? Magnetic susceptibility of a material is the property used for the classification of materials into Diamagnetic, Paramagnetic, and Ferromagnetic substances. The material is Diamagnetic if the value of…
Origin of magnetic moment
Origin of magnetic moment Magnetism originates from the spin and orbital magnetic moment of an electron. The orbital motion of an electron around the nucleus is analogous to the current…
Magnetization
What is Magnetization? Magnetization or magnetic polarization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. The origin of the…
