Electromagnetism
Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits…
Current
What is Current? An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net…
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…
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…
Important applications of dielectric material
Applications of Dielectric Material Some of the applications of dielectrics are as follows- These are used for energy storage in capacitors To enhance the performance of a semiconductor device, high…
Polarization of dielectric materials
What are Dielectrics? Dielectrics, in general, can be described as materials that are very poor conductors of electric current. They are basically insulators and contain no free electron. Dielectrics can…
Piezoelectricity
What is Piezoelectricity? Piezoelectricity (also called the piezoelectric effect) is the appearance of an electrical potential (a voltage, in other words) across the sides of a crystal when you subject…
Ferroelectricity
What is Ferroelectricity? Ferroelectricity is a property of certain nonconducting crystals, or dielectrics, that exhibit spontaneous electric polarization (separation of the centre of positive and negative electric charge, making one…
