The Earth produces its own magnetic field, which emanates from its magnetic inner iron core. On the Earth’s surface the magnetic field is extremely weak compared to the permanent magnets used in many every day appliances. At the magnetic poles the Earth’s magnetic field is approximately 0.7 Gauss compared to the Gauss value of a relatively small 10mm diameter x 5mm thick N42 neodymium magnet which can reach 5100 Gauss.
It is this magnetic field that makes a compass point north but for many species, the Earth’s magnetic field has a much more profound role…
Hi there. You may have guessed it, but I love magnets. I also love discovering awesome videos about magnets and luckily the web is full of magnet and physics videos. Here I highlight five of my favourites.
The Internet is full of useful information, including thousands of fabulous teaching resources created for every subject by teachers, schools and organisations. At first4magnets.com we are passionate about providing great, useful information about magnets for people young and old. Take a look at these free teaching resources we’ve put together.
