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 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.
