Why you shouldn’t use magnets when looking for meteorites
A popular tool for identifying meteorites can destroy scientific information
The team’s numerical calculations and experiments with earthly rocks — stand-ins for meteorites — confirmed that bringing a hand magnet close to a rock can rearrange the spins of the rock’s electrons. That rearrangement overwrites the imprint of a previous magnetic field, a process called remagnetization.
