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 ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

See all that stuff around you? Everything ... Since wire 1 has moving charges, it creates a magnetic field. Wire 2 is in the presence of this magnetic field, so it experiences a force that ...

This is called electromagnetic induction close electromagnetic inductionThe production of a potential difference (voltage) when a conductor, such as a wire, is moved through a magnetic field or ...

The Biot-Savart law states that an electrical current flowing through a wire will generate a magnetic field around itself represented by vectors that twist around like a vortex. Similarly ...
