The Earth behaves like a giant bar magnet and as such there is a magnetic field present around it. The Earth’s magnetic field is thought to be caused by flowing liquid metals in the outer core of the planet which causes electric currents and a magnetic field.

The idea of the electric field, how it's useful, and explains how the electric field is defined.

In this course you will learn about:

1. Angles and lines
2. Angles formed between parallel lines.
3. Classifying polygons.
4. Quadrilaterals.

In this lesson you will learn about:

• The concept of magnetism
• Be able to identify magnetic and non-magnetic materials
• Identify properties and types of magnets
• Understand that metals can be magnetised and de-magnetised
• Understand that magnets have a magnetic field
• Understand that the Earth has a magnetic field

The force that acts across the air gaps between magnets is the same force that creates wonders such as the Aurora Borealis. In fact, magnetic effects pervade our lives in myriad ways, from electric motors to medical imaging and computer memory. In this chapter, we introduce magnets and learn how they work and how magnetic fields and electric currents interact.

Introduction to magnetism: Wikipedia article that provides an overview of the concept.
