What causes ionic wind?

The phenomenon of ionic wind has been known about for centuries: by applying a voltage to a pair of electrodes, electrons are stripped off nearby air molecules, and the ionized air collides with neutral air molecules as it ...

Metal surface can repel electric charges

(Phys.org)—Metals are known for being good electrical conductors. Due to this property, a stationary electric point charge placed outside a metal will cause the electrons in the metal to redistribute in such a way that ...

Physicists Propose a Method to Observe Dirac Monopoles

(PhysOrg.com) -- For decades, scientists have been intrigued by the hypothetical existence of magnetic monopoles - particles with only a north or south magnetic pole, thus having a nonzero magnetic charge. But while modern ...

Study finds electrical fields can throw a curveball

MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately ...
