  • 3 Ways to Make a Magnet – wikiHow

    20190216· In nature, magnetite (also known as lodestone) is a strong, permanent natural form of magnet that was used for centuries in compasses and other objects as a magnet. Other natural magnets are weak (pyrrhotite, ferrite, and columbite), so aren’t of much use as a magnet. Manmade magnets are far more commonplace in everyday use today and come in either temporary or permanent forms.
