A moving electric charge is surrounded by a magnetic field.
... A galvanometer and a motor are similar in that they both employ coils positioned in magnetic fields. When current passes through the coils, forces on the wires rotate the coils. The fundamental difference is that the maximum rotation of the coil in a galvanometer is one half turn, whereas in a motor ...

Hall effect
![](https://en.wikipedia.org/wiki/Special:FilePath/Hall_Effect_Measurement_Setup_for_Electrons.png?width=300)
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.
