Basics of magnetism
This page covers the following topics:
The region around a magnet where a force acts on another magnet or on a magnetic material is called the magnetic field.
A permanent magnet produces its own magnetic field and is always magnetic. An induced magnet is a material that becomes magnetic when placed in a magnetic field.
The force between a magnet and a magnetic material is always a force of attraction.
The Earth has a magnetic field. This is due to the magnetic properties of the Earth’s core.
