Detailed explanation-1: -Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges.

Detailed explanation-2: -What is attraction and repulsion in terms of magnetism? Attractive magnetic forces pull two objects towards each other. For example, the different poles of two magnets are attracted to each other. On the other hand, like poles experiment a repulsive force that pushes them away from each other.

Detailed explanation-3: -Two objects containing charge with the same direction of motion have a magnetic attraction force between them. Similarly, objects with charge moving in opposite directions have a repulsive force between them.

Detailed explanation-4: -Answer and Explanation: The force between two magnets is called the magnetic force.

Detailed explanation-5: -Every magnet has a north pole and a south pole. Placing two unlike poles together causes them to attract. When you try to place two like poles together (north to north or south to south), they will repel each other. The magnets are surrounded by an invisible magnetic field that contains stored-up, or potential, energy.
