Key Stage 3
Meaning
A magnetic field is the region around a magnet that affects other magnets or magnetic materials.
About Magnetic Fields
- A magnetic field can be shown by placing a magnet under paper and then sprinkling iron filings on the paper.
- A magnetic field is strongest at the poles of the magnet.
- When a magnetic field is drawn lines are joining the north pole to the south pole of the magnet. The arrows on the field lines point from north to south.
 |
 |
| The magnetic field lines point from north to south. | Iron filings are a magnetic material so they can be used to show the magnetic field. |
Examples
 |
 |
 |
| The magnetic field of a bar magnet. | The magnetic field of Earth. | The magnetic field of an Electromagnet. |
|
| This animation shows a solar flare curving back to The Sun due to a strong magnetic field |
Key Stage 3
Meaning
This animation shows a solar flare curving back to The Sun due to a strong magnetic field.
A magnetic field is the region around a magnet that affects other magnets or magnetic materials.
About Magnetic Fields

- A magnetic field is strongest at the poles of the magnet.
- When a magnetic field is drawn lines are joining the north pole to the south pole of the magnet. The arrows on the field lines point from north to south.
