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 ...

In fact, the discovery actually supports a key part of the theory about how chorus waves work. Using data from the ...

A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation ...

Getting a magnetic field to balance on another magnetic field ... with each winding getting about 800 turns of enameled wire. The rest of the circuit is straightforward. It appears he uses a ...

Magnetic fields are everywhere in the universe ... would create a weak-but-wide-scale electrical current, like a copper wire 1,000 light-years across. Because the filtering of radiation through ...

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.
