Meteorites are not magnets – they do not attract paper clips or pins. Most (>95%) meteorites (chondrites, iron meteorites), however, do attracta magnet because they contain a lot ofiron-nickel metal.
If you have arock that does not attract a magnet, then almost certainly it is not a meteorite.Some of the rarest kinds of meteorites (achondrites, lunar meteorites, martian meteorites), however,do not attract magnets because they contain little or no metal. Most terrestrial (Earth) rocks also do not attract magnets for the same reason.
If you have a rock that does attract a magnet, then it is also probably not a meteorite because the mineral magnetite is common in Earth rocks. Cut or break the rock open. If it has metal flecks or veins like in these ordinary chondrites, then it might be a meteorite, but more likely it is just industrial slag, which often contain metal blebs.
Do not use a neodymium (rare-earth) magnet. Those things are so strong that they will attract many kinds of terrestrialrocks. An ordinary chondrite or iron meteorite will respond to an inexpensive ceramic magnet (ferrite). In the U.S. we often call these“refrigerator magnets.”
If you have a piece of metal that does not strongly attract a ceramic magnet, then it is definitely not a meteorite.
If you have a piece of metal that does attract a magnet and want to know if it is an iron meteorite, obtain a chemical analysis for the elements iron (Fe), cobalt (Co), nickel (Ni), chromium (Cr), and manganese (Mn). Iron meteorites will have 75-95% Fe, 5-25% Ni, 0.2- 2% Co, and <0.1 % (<1000 ppm) each Cr and Mn. A metallurgical lab can provide this analysis. In the right hands, a hand-held XRF analyzer can also be useful.

Magnetic: Since most meteorites contain metallic iron, a magnet will often stick to them. For “stony” meteorites, a magnet might not stick, but if you hang the magnet by a string, it will be attracted. Unusual shape: iron-nickel meteorites are rarely rounded.
Magnetism depends on how much iron is present in a rock. Meteorites vary hugely. Some are entirely made of iron, meaning that they will be attracted to magnets, and some have no iron in them at all.
Stone meteorites are worth between $2.00 and $20 per gram but could exceed $1,000 per gram. That means a one pound iron meteorite could be worth more than $2,000 while a one pound stone meteorite could get you $9,000.
Common iron meteorite prices are generally in the range of US$0.50 to US$5.00 per gram. Stone meteorites are much scarcer and priced in the US$2.00 to US$20.00 per gram range for the more common material. It is not unusual for the truly scarce material to exceed US$1,000 per gram.
First and foremost, meteorites are not harmful to humans or to any terrestrial life. Meteorite handling procedures are designed to protect the meteorite from terrestrial contamination and alteration, not to protect people from meteorites.
But be careful—not all meteorites attract magnets; only the meteorites that are rich in iron (such as iron or stony-iron meteorites) will attract magnets. Some meteorites, like those from the Moon which are only made up of rocky minerals, will not be attracted to a magnet.

All meteorites have some degree of magnetism; even the stony meteorites have flecks of iron and nickel mixture throughout the rock that distinguishes them from terrestrial rocks.
Igneous rocks tend to be more magnetic than sedimentary rocks, but there is a very wide range of overlap. Magnetic minerals include metallic iron, nickel, cobalt, magnetite, pyrrhotite, and ulvospinel.
Because magnetite has magnetic properties, it acts as a grounding stone and is thought to have powerful positive-negative polarity, meaning it attracts and repels, providing energy and a calming effect. Magnetite attracts love, commitment and loyalty.
Lodestone is a natural magnet that will attract ferrous objects. Lodestone (Fe3O4) is a natural magnet that will attract objects such as staples, iron filings and needles. When suspended by a thread, it will align along a north-south axis, which is the principle of the compass. This is a naturally occurring item.
Also, don't forget your metal detector. "Most meteorites contain at least some metallic iron-nickel and so will be at least somewhat magnetic and set off metal detectors," Rubin wrote in an email.
They show that exposure to a magnet can reorient a rock's microscopic grains, undoing their original orientation and any trace of its magnetic origins. The researchers make their case with Northwest Africa (NWA) 7034, a meteorite known in collectors' circles as “Black Beauty” for its obsidian exterior.

Touching even a small magnet to a meteorite can erase any record the rock might have retained about the magnetic field of its parent body, researchers report in the April Journal of Geophysical Research: Planets.
