Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how ...

If you grew up around some of the earlier models of televisions and computers, you may have received at least one sternly-worded warning to never place a magnet near them. These warnings still persist ...

Astrophysicist Tomoaki Matsumoto and collaborators have used three-dimensional magnetohydrodynamic supercomputer simulations ...

Atomic scale copper rich layers inside rare earth magnets suppress demagnetization, improving strength, stability, and efficiency in motors and generators. (Nanowerk News) Rare-earth magnets are ...

The third type of magnetism could prove the most useful of all—if researchers can identify the materials that exhibit it.
