Lesson Details
Key learning points
- Magnets can be different sizes and shapes.
- There are different types of magnets, including bar, ring, button and horseshoe.
- Scientists refer to the poles of a magnet as a north-seeking (N) pole and a south-seeking (S) pole.
- Magnets always point north because Earth acts like a giant magnet. Its core contains iron, which is magnetic.
Common misconception
All magnets look the same. The poles of all magnets are the ends.
Real examples and diagrams of different magnets and their poles will be given.
Keywords
Magnet - A magnet is an object that can attract magnetic materials, such as iron and steel.
Poles - Every magnet has two poles, and on a bar magnet, these are at opposite ends of the magnet.
North-seeking - The north-seeking pole of a magnet is the part that points north when the magnet is allowed to move freely.
South-seeking - The south-seeking pole of a magnet is the part that points south when the magnet is allowed to move freely.
