Ferromagnets are characterized by a magnetization that has long been used to store information. The magnetization is largely due to localized electron spins with their associated magnetic moments ...

Back when I was a kid, we had these things called compasses. It's just a magnetic needle inside a case that is free to rotate. Since a magnetic field can exert a torque on another magnet, this needle ...

Motors are machines that convert electrical energy into mechanical energy using magnetic forces. When current is passed through a wire loop that lies in a magnetic field, a turning force, or torque, ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged particles. When you purchase through links on our site, ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...

The reason for copper's unique properties comes down to the configuration of its electrons. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Wires ...

Our protective blanket helps shield us from unruly space weather. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Earth's magnetic field — also ...

To say that the Earth's magnetic field is important would be an understatement. It's one of the reasons we live on this pretty little rock tumbling through space, and it also gives us the gorgeous ...
