... The first term of eqs. (47) and (50) could be called the retarded Coulomb field, and the first term of eqs. (48) and (51) could be called the retarded Biot-Savart field. Both of these terms vary as the inverse square of the distance between the source and observer, and so they are important in the near ...

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.
