... Rather than drawing the conductor as a cylinder and using an arrow to indicate direction, it is often more convenient to use a two-dimensional picture, as in Figure 4. A circle is used to represent a cross-section of the conductor. A circle with an X in it represents an electric current moving into ...

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.
