Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that ...

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the ...

The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

Abstract: Magnetic tracking methods provide a radiation-free, contactless solution for real-time localization, making them widely applicable to medical diagnostics and robotic navigation. The scalar ...

Abstract: With the development of switching devices toward high frequency, the prediction and calculation of magnetic material losses under high frequency have become increasingly important. Moreover, ...

A physical quantity is something that can be measured. Scalar quantities only have size (or magnitude). Vector quantities have size and direction. Speed is a scalar quantity - direction is not ...
