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 ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when ...

While the Florida panhandle was hammered by inclement weather on Monday, Tallahassee was mostly unscathed by the severe ...

It weighs in at just 21 milligrams and has a wingspan of only 9.4 millimeters. The device flies when exposed to an external ...

This prototype includes, among other characteristics, the limiting magnet geometry and relevant magnetic field strength in its Infinity Two fusion power plant. The prototype’s technology that has ...

Two researchers who independently developed the neodymium magnet — used in everything from hard disk drives to automobiles — have been awarded the 44th Honda Prize. In 1982, two researchers ...

US fusion start-up Type One Energy said early results from its testing campaign confirm the essential design elements of ...

Magnetism has traditionally come in two varieties ... with ferromagnetism (FM), like a refrigerator magnet or compass needle, where magnetic moments in atoms lined up in parallel in a crystal.

In their experiments with FGT, a metallic magnet made of iron, germanium, and tellurium, the research team achieved two ... magnetic moment in bulk material can be reversed by a very weak field ...
