In 1820, Danish physicist Hans Christian Ørsted noticed a compass needle move when placed near a live electrical wire. This proved that electricity generates magnetism. electromagnetism for dummies pdf updated

The light you see with your eyes is just a tiny slice of the broader . Depending on how fast these waves vibrate (their frequency), they take on different forms: For the independent learner, some of the most

The reverse is also true. If you move a magnet near a wire, or change the strength of a nearby magnetic field, you (create) an electric current in the wire. This is called electromagnetic induction . This proved that electricity generates magnetism
