There are 9 lessons in this physics tutorial covering Introduction to Magnetism. The tutorial starts with an introduction to Introduction to Magnetism 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 Introduction to Magnetism. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• What are magnets?
• How many types of magnets are there?
• What is magnetic field? How do we represent the magnetic field?
• What are magnetic poles? What do they have in common with Earth Poles and where do they differ?
• What is magnetic force? What happens when we bring like and unlike poles close to each other?
• How a magnet is produced?
• How to remove magnetism from a magnet?
• What magnetic tool do we use to orient ourselves when no direction is known?
• What is magnetosphere? How does it protect us?
• How magnetism is used by animals?
• How do we use magnetism in electrical equipment? Medicine? Industry?

## Introduction

What happens when you bring a magnet near a small iron object such as needle, bolt, etc.? Is it necessary to touch them to observe this phenomenon?

Try putting some iron filings on a paper and move the magnet slightly below the paper for a while. What do you observe? Do the iron filings spread irregularly throughout the paper or not? Explain.

This tutorial is an introduction to magnetism - the other sub-branch of electromagnetism, which is one of the building blocks of physics.
