Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not ...

The magnets create a gradient of 1.13 T/m ... The MPI system also incorporates a water-cooled 26.3 kHz drive coil, which produces the oscillating magnetic field (of up to 7 mT peak) needed to drive ...

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.

Electromagnetic induction (EI), or the production of voltage across a conductor by varying the magnetic field or by ... the magnetic flux gradient at the position of the coil winding, leading ...
