Electromagnetic Force: Definition in Dynamics - QS Study
top logo

Electromagnetic Force: A kind of force exists between two charged bodies and between two magnetic materials. These are called Coulomb’s electric force and magnetic force respectively. Electric and magnetic force can either be attractive or repulsive. The electric and magnetic forces are closely related to each other. Actually, the force acting between charged particles in motion is electromagnetic force. When the charges are in motion then they produce magnetic field. Again, varying magnetic held act; as a source of electric field.

The electromagnetic force acts between charged particles and is the combination of all electrical and magnetic forces. The electromagnetic force can be attractive or repulsive. Aside from gravity, the electromagnetic force is responsible for all forces we experience directly (the only other two known fundamental forces are the “strong force” and the “weak force,” which hold together the particles in the nucleus of an atom). For example, the electromagnetic force holds atoms together in molecules, causes friction, and attracts iron to a magnet.

Electromagnetic force is demonstrated in elastic force, molecular structure, chemical reaction etc.
