## Theory of Electric Field – Why electric field lines can never Intersect?

A point charge at rest creates a force field in its surrounding. This force filed is known as Electric Field. You can understand force field like a field created by a magnet in its surrounding due to which iron piece get attracted toward the magnet....

## Faraday’s Law of Electromagnetic Induction

Faraday’s Law: Faraday’s Law of Electromagnetic Induction states that, whenever the flux of magnetic field through the area bounded by a closed conducting loop changes, an emf is produced in the loop. The produced emf is given by ξ = -dØ/dt   where Ø = ∫B.ds...

## Lenz’s Law – Direction of Induced Current

Lenz’s Law states that the direction of the induced current is such that it opposes the change that has induced it. In other words, lenz’s law is defined as Effect Opposes the Cause. Lenz’s Law is used to find the direction of induced current in a conducting...

## What is Eddy Current? – Concept of Electromagnetic Damping

What is Eddy Current? The literal meaning of Eddy is a circular current. Thus the word itself means current having no definite circular loop. Eddy current is defined as the induced current on the surface of conductor in little loops or eddies due to changing...

## Gauss Law and its Application

Gauss Law states that, the flux of net Electric Field through a closed surface is equal to the net charge enclosed by the closed surface divided by permitivity of space. Therefore, mathematically it can be written as ∫E.ds = Qint/ξ     (Integration is done...

## Why Electric Field inside a Conductor is Zero?

In this post we will discuss, why electric field inside a conductor is zero. This is very basic but important concept to understand. So we will start will zero and will move further to explain this. Let us assume that a conductor is kept in...

## Coulomb’s Law

Coulomb’s law is an experimental law formulated in 1785 by the French colonel, Charles Augustin de Coulomb. It deals with the force a point charge exerts on another point charge. By a point charge we mean a charge that is located on a body whose...
