Electromagnetism - Electrostatic Force: The Four Fundamental Forces of Physics #4a
How does an Electromagnet Work?
Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force usually exhibits electromagnetic fields such as electric fields, magnetic fields and light, and is one of the four fundamental interactions in nature. The other three fundamental interactions are the strong interaction, the weak interaction and gravitation.
