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

Torque by magnetic pull. March 1, 2006. ... The rotating magnetic field sets up opposing electrical eddy-current fields in the conductive disc, ...

Physicists at the University of Illinois at Urbana-Champaign have observed a magnetic phenomenon called the 'anomalous spin-orbit torque' (ASOT) for the first time. Professor Virginia Lorenz and ...

Figure 2: Spin-torque switching and magnetic-field-induced switching characteristics of an Al-passivated device. a , Current scan taken at 4.2 K demonstrating a characteristic spin-torque ...

The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...

Electric Motor: In this 4th article on the ‘Journey of the electrical motor ‘, “we revisit our discussion on the relative angle between the magnetic fields. To achieve a particular torque ...

Faraday’s Law of Induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor.

Electric vehicles are obviously different from gas-powered cars, but do they have engines? We explore how EV motors and drivetrains work.

Most standard software for modeling magnetic fields uses the standard finite-element method. For some problems, however, an alternate boundary-element formulation can be much more efficient.

Physicists have observed a magnetic phenomenon called the 'anomalous spin-orbit torque' (ASOT) for the first time. Scientists have made this observation, demonstrating that there exists ...
