🧲 The Discovery That Lights the World
In 1831, Michael Faraday pushed a bar magnet into a coil of wire — and a current flowed. He pulled it out — and a current flowed in the opposite direction. He held the magnet still — nothing. This seemingly simple observation is the foundation of almost all electricity generation on Earth. Every wind turbine, every hydroelectric dam, every coal and gas and nuclear power station uses this exact principle — a magnetic field changing near a conductor causes a current to flow. Without electromagnetic induction, there would be no mains electricity, no dynamos, no transformers, and no modern civilization as we know it. Faraday's coil experiment is one of the most consequential moments in the history of science.
