There are 4 lessons in this physics tutorial covering Faraday's Law of Induction. The tutorial starts with an introduction to Faraday's Law of Induction 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 Faraday's Law of Induction. you can access all the lessons from this tutorial below.
In this Physics tutorial, you will learn:
- What are the quantities (variables) Faraday analysed to make his discoveries in Electromagnetism?
- What is induced current and induced emf?
- What factors do affect the induced emf produced in the presence of magnetic field?
- What does the Faraday's Law of Induction say?
- What is magnetic flux? What is its unit?
- How can we change the magnetic flux in a coil?
- Why the induced emf is also known as motional emf?
- How are the motional emf and electrical energy related to each other?
- The same for the motional emf and electric power
Introduction
So far, we have seen many examples in which a current carrying wire produces a magnetic field around it. What about the reverse process, i.e. do you think a simple magnet can produce electricity?
How do we call the method of charging objects by bringing another charged object near a neutral one? Do you think this phenomenon is related in any way to the current topic?
This tutorial discusses a phenomenon known as "induced current". This is not a current produced by direct contact between objects; this means it is different from the current we have seen so far.
