# Electromagnetic

electromagnetic force is a type of physical interaction that occurs between electrically charged particles. The electromagnetic force usually shows electromagnetic fields, such as electric fields, magnetic fields, and light. The electromagnetic force is one of the four fundamental interactions in nature i.e. Electromagnetic force, strong interaction, the weak interaction, and gravitation.

vCalc's Electromagnetic folder contains equations pertaining to Electromagnetic Theory.
