Electromagnetic devices, from power drills to smart-phones, require an electric current to create the magnetic fields that allow them to function. But with smaller devices, efficiently delivering a current to create magnetic fields becomes more difficult.
 
In a discovery that could lead to big changes in storing digital information and powering motors in small hand-held devices, researchers at UCLA have developed a method for switching tiny magnetic fields on and off with an electric field — a sharp departure from the traditional approach of running a current through a wire.
