Physicists have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. Scientists ...

Magnetic rotation and antimagnetic rotation represent distinct mechanisms by which atomic nuclei generate angular momentum in systems that exhibit little or no permanent quadrupole deformation. In ...

Oh, those twinkling, twinkling little stars. They make the night sky seem so peaceful, so idyllic, so quiet. It’s hard to believe that they are actually powerful furnaces, where explosive power, ...

Solve a rotating-coil electromagnetism problem by deriving the induced emf from changing magnetic flux. Learn how coil area, number of turns, rotation rate, and magnetic field strength set the emf ...

The joint research team was led by Prof. WANG Hui and Prof. ZHANG Xin from the High Magnetic Field Laboratory, Hefei Institutes of Physical Science. In recent years, magnetic nanoparticles (MNPs) have ...

A neutron star is the extremely compressed leftover core of a star that began life with between 10 and 30 times the Sun’s mass. Moving charges do generate magnetic fields, as you suggest; however, the ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

• Magnetic bearings support rotating shafts in five axes without solid or fluid lubricants. • Advances in electronics allow previously bulky controllers to mount on or near rotating machinery. • ...

Discover how a rotating coil placed in a magnetic field generates an induced EMF. This video explains the core physics behind electromagnetic induction, showing how motion, magnetic flux, and ...
