Magnetite is a special kind of rock. It sticks to magnets. Magnetite is made of a metal called iron. The iron is what sticks to magnets.

Pieces of the mineral magnetite that have been magnetized naturally are lodestones. They are magnets that are present in nature and may draw iron. Using lodestones, the phenomenon of magnetism was first discovered in antiquity. The best magnets for this test are rare earth magnets, which are inexpensive, widely available, and effective. However, there are earth rocks that can also hold a magnet, and to make matters worse, these rocks are fairly typical. Hematite and magnetite-containing rocks and minerals are the two types of rocks that are most frequently misinterpreted. For collectors and researchers, meteorites are highly valuable in terms of money and science. From a few dollars to hundreds of thousands of dollars, meteorite values can vary. Sedimentary, metamorphic, and igneous rocks all contain magnetite.
