Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.
Examples of electromagnetic devices include doorbells and any devices that have electric motors, such as electric fans. The electromagnet in a doorbell attracts the clapper, which hits the bell and makes it ring. An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy.
