... A free swinging magnet will point north with its north seeking pole-that end is marked with an N. Like electrical charges, opposite forces between magnetic poles attract, N-S, positive –negative Like poles repel: south repels south; north repels north Magnets keep their poles even when cut in two. A ...

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.
