The Mechanical Universe

The Magnetic Field. All magnetic fields can be thought to be produced by electric currents. The relationship between a current and the magnetic field it produces is somewhat peculiar geometrically and takes some getting used to. The law of Biot and Savart, the force between electric currents, and Ampere's law. (from themechanicaluniverse.org)
