Representing Vector Fields Using Field Line Diagrams
... An array of field lines is called a field line diagram, and it is a way of representing both the direction and the strength of a vector field. The direction is found by focusing on an individual field line, as above. The strength is found by looking at the density of field lines. For example, the fi ...

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.
