Steel is a mixture which also contains iron, so it is a magnetic material as well, as iron oxide is a compound that can be made into a magnet by stroking it in the same direction. Not all metals are magnetic materials. It is possible to find natural magnets out of rocks or minerals but most magnets nowadays are manmade or manufactured.

Every magnet has a north and south pole. The north pole, also known as the north-seeking pole, attracts the south pole/south-seeking pole, while it repels the same pole.

Magnetism is extremely useful, and we can normally ...
