Magnets are amazingly strong... but there's a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!

Magnets - how DO they work? We've got the answer for you, plus a bunch of weird fun magnet facts - where they got their names, why hitting some stuff with a hammer can turn it into magnets, and even why we feed magnets to cows, on purpose.

Materials can be classified based on their response to external magnetic fields. Diamagnetic materials are weakly repelled by external magnetic fields, while paramagnetic materials are attracted but lose their magnetism in the absence...

You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if...

AP Physics C: Electricity and Magnetism review of magnetic fields including: the basics of magnetic dipoles, ferromagnetic and paramagnetic materials, the Earth’s B field, magnetic permeability, the magnetic force on a moving charge, the...

In this video, we learn about the components and functions of a hard drive, a data storage device used in computers. The video explains how data is stored and retrieved and how it reads and writes data without physical contact. It also...
