Meteorite Identification: Have you found a space rock?

Meteorite Identification: The Magnet Test. Meteorites are divided into three basic groups: irons, stones, and stony-irons. Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test.
