Inductors control electric current by using magnetic fields to resist sudden changes. This video explains how a simple coil can manage current flow and stabilize circuits in many electronic devices. A ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

A research team at Tohoku University has shown that a steady electric current can hold electron spins in positions that should be impossible to maintain, effectively forcing magnetization to point the ...
