What is Electric Field – Definition, Calculation and Example

Definition: 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. Another example of force field is gravitational field. Thus, … Read more What is Electric Field – Definition, Calculation and Example

Faraday’s Law of Electromagnetic Induction

Faraday’s Law: Faraday’s Law 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 is the flux of the magnetic field through the area. Ø is called the … Read more Faraday’s Law of Electromagnetic Induction

What is Lenz’s Law?-Definition with Diagram

Definition: 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, it is defined as “Effect Opposes the Cause”. Lenz’s Law is used to find the direction of induced current in a conducting loop. As per Faraday’s Law of electromagnetic induction, a current … Read more What is Lenz’s Law?-Definition with Diagram

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 magnetic flux. To better understand the concept of eddy current, … Read more What is Eddy Current? – Concept of Electromagnetic Damping

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 an external uniform electric field E. The direction of electric … Read more Why Electric Field inside a Conductor is Zero?

Basics of Magnetic Circuit

Magnetic Circuit is defined as the path followed by a Magnetic Flux. Magnetic Flux always has a tendency to follow low Reluctance path. The laws of Magnetic Circuit are quite similar to the Electric Circuit but the terms used in Magnetic Circuit analysis is different. Let us consider a Toroid having a magnetic path of … Read more Basics of Magnetic Circuit
