Historically, prior to 1820, electricity and magnetism were thought to be separate entities of nature. On April 21, 1820, Hans Christian Oersted, a Danish physi ...

Unlock the secrets of Maxwell’s Equations and discover how they govern light and electromagnetism. In this video, we break down each equation, explain the physical meaning behind them, and show how ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Magnets, how do they work? Although the quantum mechanics behind ferromagnetism are by no means easy, a few simple experiments can give you a good grasp of how magnets attract and repel each other, ...

This video explores the nature of magnets and how they create invisible magnetic forces. It explains the origin of magnetism, how magnetic fields are formed, and the role of electrons in generating ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

There is a tangled web of magnetism running across the Milky Way. Although you cannot see it with your eyes, this fundamental force winds through the spiral arms and influences everything from the ...
