What does a magnet have to have to be a magnet?

To be a magnet, an object must have a magnetic field, which is typically produced by the alignment of its atomic or molecular structure, particularly the electrons' spins. Most magnets are made from ferromagnetic materials like iron, cobalt, or nickel, which can be magnetized. A magnet must also possess two poles: a north pole and a south pole, which create the magnetic force that attracts or repels other magnetic materials.
