If Michael Faraday was alive today, we might say that he hacked electricity and magnetism. In 1821, he knew that the flow of current produced a magnetic field, and he wondered if a magnetic field could produce the flow of current. The next year, he wrote in his laboratory notebook, “Convert magnetism into electricity.”1
A few years later in 1831, he conducted an experiment where he wrapped one side of an iron ring with several turns of insulated wire, and on the other side of the ring, he did the same. One of the coils of wire was connected to a battery and the other was connected to a galvanometer (or an amp meter or ammeter) so he could detect ...
