Michael Faraday · Science
Faraday’s 1831 discovery that a <em>changing</em> magnetic field drives an electric current - the iron ring, the moving magnet, and the spinning disc that became every generator on Earth.
You learned that Faraday found electricity is induced not by magnetism but by changing magnetism (motion, or the making and breaking of a magnetic field), and that this single fact underlies the generator, the motor, and the transformer. Explain how induction works and why change is essential.
Leads to Hans Christian Ørsted.
