Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.In physics, several different types of magnetism are distinguished. Ferromagnetism (along with the similar effect ferrimagnetism) is the strongest type and is responsible for the common phenomenon of magnetism in magnets encountered in everyday life.

Because iron is strongly magnetic, you can extract it from any type of beach sand with a magnet. Construct a drum magnet, which offers a more efficient way to extract a large volume of iron than passing a flat magnet over the sand. To construct the magnet, you'll need a length of 4-inch PVC pipe, some permanent magnets and some two-part epoxy ...
