How A Twitching Compass Revealed a Universal Secret

"⚡️🧭 In 1820, a simple experiment in a lecture hall led to one of the most profound discoveries in science. This video tells the story of Hans Christian Ørsted and the moment he realized that a twitching compass could reveal a universal secret: that electricity and magnetism are two sides of the same coin. Join us as we explore the discovery of electromagnetism
We break down the historical context of the discovery, explaining what scientists believed before Ørsted's experiment. We'll then walk you through the experiment itself, showing how an electric current creates a magnetic field. Finally, we'll discuss the monumental impact of this finding, paving the way for the work of Michael Faraday and James Clerk Maxwell, and leading to the development of electric motors, generators, and the entire electrical civilization we live in today.
