Learn how to perform a vector magnetic field calculation using two current-carrying wires in this clear, step-by-step physics tutorial. We break down key concepts like the Biot–Savart law, vector ...

A nanodevice developed at EPFL produces an autonomous, stable current from evaporating saltwater by using heat and light to control the movement of ions and electrons. Previously, researchers in the ...

From DIY levitation tricks to clever braking systems, these swirling paths of electrons keep finding new ways to surprise and inspire.

Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet—or understand why. Triplet superconductors could be the key to achieving ...
