There are 2 lessons in this physics tutorial covering Lentz Law. The tutorial starts with an introduction to Lentz Law and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Lentz Law. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What is the definition of Lentz Law? What do we find using it?
  • How the Lentz Law is related to the Faraday's Law of Induction?
  • What strategy do we use to solve problems involving the implementation of Lentz Law?
  • What is the induced magnetic field? When does it appear?
  • What happens to the magnetic flux when a magnet moves towards to or away from a coil?

Introduction

You are walking near a dangerous dog. What do you do in this case? Is it a good idea to assault the dog first in order to protect yourself? Why? What is the best thing to do in this case?

What is the direction of induced current produced in a coil? How do you know this?

What happens to the magnetic flux when we move a magnet towards or away from a coil?

This tutorial explains the rules how to determine the direction of induced current flow in a magnetic field. We have already touched this topic earlier but now we will explain it more extensively, in order to provide a full explanation of this phenomenon (induced current).
