Faraday

In 1820, Hans Christian Oersted noticed a compass needle deflect near a current-carrying wire — accidentally unifying electricity and magnetism and launching the age of electromagnetism.

Michael Faraday's 1821 rotating wire became the device that now consumes 50% of the world's electricity. Here's how the electric motor works and why Tesla's AC design won.

Electricity was a scientific curiosity in 1800. Within 100 years it was lighting cities and running factories.

Humans observed static electricity for millennia before understanding it. Then in 100 years, we went from Volta's first battery to electrifying entire cities.

In 1831, Michael Faraday discovered that changing magnetic fields induce electric currents. This fundamental discovery enabled electric motors, generators, and transformed civilization.
