In physics, magnetism is one of the forces in which materials and moving charged particles exert attractive, repulsive force or moments on other materials or charged particles. Some well-known materials that exhibit easily detectable magnetic properties (called magnets) are nickel, iron, cobalt, gadolinium and their alloys; however, all materials are influenced to greater or lesser degree by the presence of a magnetic field. Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. They include copper, aluminium, water, and gases.

Magnetism also has other definitions and descriptions in physics, particularly as one of the two components of electromagnetic waves such as light.
