What is the history of electricity and magnetism?

Magnetism was first discovered in the ancient world, when people noticed that lodestones, naturally magnetized pieces of the mineral magnetite, could attract iron. The word magnet comes from the Greek term magnētis lithos, "the Magnesian stone, lodestone."

In the history of electricity, no single defining moment exists. The way we produce, distribute, install, and use electricity and the devices it powers is the culmination of nearly 300 years of research and development. Efforts to understand, capture, and tame electricity began in the 18th century.
