If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field. In this situation they act as a magnet - but only whilst in ...

This pioneering technology marks the world's first achievement in this field. The findings are ... However, conventional permanent magnet manufacturing processes have been heavily dependent ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

A new prototype is laying claim to the title of smallest, lightest untethered flying robot. At less than a centimeter in ...

As [The Thought Emporium] explains in more eloquent detail, a magnet under the skin allows the implantee to gain a permanent sense of strong magnetic fields. Implantation in a fingertip is most ...

They have shown the generation and application of magnetic field steps, in which a magnetic field is turned on in a matter of picoseconds. The work has been published in Nature Photonics.

Superconductors aside, these devices are pretty much all operating in the same way; an object with a permanent ... magnet can not only be levitated, but locked in place using a rotating magnetic ...
