This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

Physicists have discovered that electronic excitations in 2D magnets can interact through spin waves – ripples in a ...

As it turns out, the ability to nullify the powerful magnetic field from a bunch of rare earth permanent magnets is as simple as bringing in another set of magnets to cancel out the magnetic ...

This is due to their relatively low Curie point, which is the temperature above which a substance loses its magnetic properties. At room temperature, a pure bar ... N 2 is then separated by magnet ...
