Magnetism and Alternating Current
... The relay is a device used to control a large flow of current by means of a low voltage low current circuit. It is a magnetic switch. When the coil is magnetized, its attractive force pulls the lever arm, called an ARMATURE, toward the coil. The contact points are touched and the large current flows ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
