- Magnet - Wikipedia
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, such as iron, steel, nickel, cobalt, etc and attracts or repels other magnets
- Magnetism | Definition, Examples, Physics, Facts | Britannica
Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital Learn more about magnetism in this article

Just as electric charges have electric fields surrounding them, magnets have magnetic fields that surround them This page explores the important concept of the magnetic field and how magnetic field lines communicate its strength and direction
- What Are Magnets Made Of? | Magnet Basics
When an atom – such as iron – has an odd number of electrons, those unpaired electrons create a magnetic field, turning the entire atom into a tiny magnet When most atoms in an object are tiny magnets, it produces an overall magnetic field with a north and south pole
