Substances form natural magnets

Web1 Apr 2024 · Geology. Magnets can be made and can be found in their natural form. Natural magnets are from the stone magnetite (loadstone) and were first discovered in the region known as Magnesia (in Greece) nearly 2000 years ago. No matter what type of magnet you have, they all have the property of magnetism. WebTwo materials found in nature, lodestone (or magnetite, an oxide of iron, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets. They were discovered more than 2,000 years ago, and all early scientific studies of magnetism were conducted on these materials.
