What is Electromagnetic?

Electricity and magnetism are two types of fields in physics that are studied together with the forces they cause. It is shown in Maxwell's equations how electricity and magnetism are connected. Electric charges, currents, magnetic fields, and electromagnetic waves all behave in a certain way because of these rules. Electric motors, antennas, transformers, and wireless transmission are all built on top of it.
