Magnetic Fields Round a Solenoid

This picture, entitled Magnetic Field of the Solenoid, illustrates the magnitude and direction of magnetic field lines around a solenoid. A solenoid is a loop of wire that encircles a charge-carrying core, usually metal, and acts as a magnet when electricity travels through it. The researchers approximated the magnetic field in the image by using the superposition of two-dimensional point sources using the Biot-Savart Law.
