There are four fundamental equations that represent the electromagnetic behaviour in the universe, these are called Maxwell’s equations. His four equations are as follows:
The first of Maxwell’s equations proves a concept most people are already aware of, this is that electric dipoles are preset in nature. An electric dipole is either a single positive charge or a single negative charge (a proton or an electron). To prove this claim we can use some snazzy diagrams.
