In 1862, James Clerk Maxwell published his famous Maxwell’s equations. This was at a time when humans were just starting to ...

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.

The induced magnetic field of a wire can interact with other nearby magnets, producing a force. Electromagnetic induction - Higher - OCR Gateway Electromagnetic induction can create a voltage.

Over two centuries ago, physicist Michael Faraday described how electric current running through a coil of wire can create a magnetic field. This magnetic field can then induce an electric field ...

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 ...
