Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

For decades, ferromagnetic materials have driven technologies like magnetic hard drives, magnetic random access memories and ...

They test three different magnets and measure the distance that each magnet is able to attract a paper clip. To make the test fair, they use the same ruler and paper clip throughout.

Permanent magnet homopolar inductor machine (PMHIM) has attracted much attention in the field of flywheel energy storage system (FESS) due to its merits of simple structure, brushless excitation, and ...

A temperature compensated magnetic field sensor using magnetic fluid (MF) filled exposed core fiber (ECF) has been proposed to detect magnetic field strength and temperature (MFT) simultaneously in ...

Magnetic nanomaterials in magnetic fields can serve as versatile transducers for remote interrogation of cell functions. In this study, we leveraged the transition from vortex to in-plane ...
