Faraday Law of Electromagnetic Induction | EMI | Lenz Law Simulation | Electromagnetic Induction | PhET Simulations

Here you will understand the conceept of Faraday's Law of Electromagnetic Induction (EMI) and Lenz's Law with the help of a beautiful simulation.
This simulation of electromagnetic induction explains the concept of induced EMF in a coil, when there is a relative motion between the bar magnet and the coil.
The formula of Faraday's law of electromagnetic induction has been made clear experimentally with the help of this simulation.
At the end of this video, it explains the Lenz Law with simulation.
After watching this video you will understand that, negative sign used in the formula of Faraday's law of electromagnetic induction is because of the lenz's law.
This simulation video has been created by using phet simulations (phet Sims).

Faraday's Law of Electromagnetic Induction 

According to the Faraday's Law of Electromagnetic Induction, if a conductor is placed in a varying magnetic field then emf (electromotive force) is induced in the conductor. If the conductor circuit is closed then current is induced which is called as induced current. This induced emf is equal to the rate of change of flux linkage with the coil.

Lenz's Law definition

Lenz's law states that the direction of the induced current produced in this phenomenon is such that the magnetic field produced by this induced current opposes the magnetic field that produced it.

  1. Students who are appearing for the West Bengal 12th Class Examination are in the right place. It will be an added advantage for the students if they go through the WB Model Paper 2022 for HS. WBCHSE Model Paper 2022 Every student has a different learning style, so after finishing the preparation of each subject, it will be an added advantage if the student goes through these sample papers to score high M. WBCHSE Model Paper 2022 for 12th Class is an Important Tool that will assist students in obtaining higher marks in the Final Exam 2022. WBCHSE Model Paper 2022 has been prepared by Senior Experts.
