What Does Electromagnetism Mean?
Electromagnetism is a branch of physics which deals with study of electromagnetic force. Being one of four fundamental interactions – along with gravitation, weak interaction and strong interaction – electromagnetic force happens between electrically charged particles. Discovered in the 19th century, electromagnetism has extensive usage in todays’ physics.
Techopedia Explains Electromagnetism
Electromagnetism can be considered as the science of electromagnetic fields. When an electric current passes through a conductor, a circular electromagnetic field is created around it. The direction of the current decides the direction of rotation of the created magnetic field. The current strength as well as length of the conductor decides the force of electromagnetism developed. Change of the magnetic field can produce electricity.
