Make your own easy model of magnetic Earth

Continuing our theme of magnetism, the ELI today is 'Recipe for a magnetic Earth and a magnetic detector; using a stress ball and small magnet, with a needle and thread to model magnetic Earth'

Once pupils have made their ‘magnetic Earth’ this can also be tested using a Magnaprobe™ to show the direction of Earth’s magnetism at different altitudes.

Many activities related to magnetism can be found on our website.

Measuring changes in magnetic declination to investigate the Earth’s core

The new ELI (published a few weeks ago) was 'Magnetic Manchester; measuring changes in magnetic declination to investigate the Earth’s core'.

The Earth’s changing magnetic declination, recorded at the world’s airports, can
be used as evidence for the composition and nature of the Earth’s core.
