The film discusses the historical development and principles of electrodynamics, starting with Luigi Galvani's chance discovery of electric current through the twitching of a frog's leg. It explains ...
If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...
Albert Fert, French physicist and winner of the Nobel Prize in Physics in 2007, is one of the discoverers of giant magnetoresistance, a physical effect that revolutionised hard disk technology, ...
Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. To the uninitiated, electricity might seem like a sort of hidden ...
"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...
In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...
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 ...
Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...
Superconductivity and magnetism have long been treated as rivals in condensed matter physics, one thriving on perfect ...
