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, and attracts or repels other magnets.
Magnetism is an aspect of Electromagnetism, whereby materials can exert attractive or repulsive forces at a distance. It is a non-contact force ( also known as a field force). Every electron is a tiny magnet. Usually the electrons inside the materials are randomly aligned giving rise to undetectable magnetic field. However, when all these tiny magnets get aligned in a particular direction, the magnetic field becomes noticeable.
