Everything You Need to Know About Rare Earth Magnets
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets. A permanent rare earth magnet is one made from a material that stays magnetized.

Rare Earth Magnets – The Ultimate Guide
Rare earth magnet properties define the core aspects that describe a magnet's strength. These properties include: Coercivity. The tendency of a magnet to resist demagnetization defines its coercivity. It defines a rare earth magnet's ability to maintain its magnetic field strength when subjected to demagnetizing factors.
