Etymology
Magnetism named the characteristic properties of a magnet. With the electrical element, the compound became a collective name for phenomena linking electric currents and magnetism—the connection central to the modern force sense.
In context
a turbine spins a magnet inside a coil to produce electricity and since electromagnets need a power source this turbine is powered by wind so you can see why electromagnetism is an incredibly important force
