According to Faraday, the poles of a magnet brought a loop of induced wire toward them to produce power. A magnetic field in constant change generates electromotive force in electric conductors via ...

Uncoated tape used to separate other sections of tape is called leader. Magnetic tape superseded the earlier magnetic wire recorders after World War II because of the ease with which one could splice ...

Merging some esoteric physics principles with an advanced instrument creates a magnetic microscope with resolution better ...

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 ...

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.
