You cannot have magnetism without moving charge (except for the quantum spin in permanent magnets). He hovered the copper-wrapped nail over a heavy steel wrench
into motion! By waving his magnetic arms back and forth, he "induced" to start running through the circuit. This became their secret handshake, known to the world as Electromagnetic Induction . It’s how every power plant on Earth works: Then a pair of pliers

For a long time, people thought electricity (static shocks, lightning) and magnetism (compasses, fridge magnets) were totally separate. In 1820, Hans Christian Ørsted noticed a compass needle move near an electric wire—proving they are linked. Electricity: The flow of electrons through a conductor. Magnetism:
Understanding how electric fields spread out from charges [5].
