Magnetic Attraction
Meteorites are not magnets – they do not attract paper clips or pins. Most (>95%) meteorites (chondrites, irons), however, will attract a magnet because they contain a lot of iron-nickel metal. If your rock does not attract a magnet, then it is almost certainly not a meteorite. If you have a piece of metal and it does not strongly attract a magnet, the it is definitely not a meteorite.
If you have a rock that does attract a magnet, then it is also probably not a meteorite because magnetite-rich Earth rocks are much more common than meteorites. Cut or break it open. If it has lots of metal flecks or veins like these ordinary chondrites, then it might be a meteorite (but industrial slags sometimes contain metal).
A good way to test if a rock is attracted to a magnet is with a circular ceramic magnet like those often used for “refrigerator magnets.” Put it on its edge on a flat, hard surface. If a rock attracts a magnetic, you can cause the magnet to roll by pulling the magnet with the rock.
Don’t use a neodymium (rare earth) magnet. Those things are so strong that they will attract many kinds of terrestrial rocks. An ordinary chondrite will respond to a simple refrigerator magnet.
Magnetite (the rock at the end of the ruler) is a common Earth mineral. It readily attracts a cheap refrigerator (ceramic) magnet.
