Inductors control electric current by using magnetic fields to resist sudden changes. This video explains how a simple coil ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

A research team at Tohoku University has shown that a steady electric current can hold electron spins in positions that ...

A research team has discovered a new way to control tiny magnetic properties inside materials using electric current, which could possibly pave the way for new types of computing technologies. The ...
