When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

Experiment Generates Current from Earth's Magnetic FieldS cientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field ...
One way to get moving charges is to run electric current through a wire. (This is literally a stream of electrons.) This will create a magnetic field, and other wires with electric current will ...
Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are ...
A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.
Indeed there is, in addition to the obvious ways to manipulate the spin using magnetic fields, an indirect effect on the electron spin from externally applied electric fields, due to the so-called ...
