the effect of a magnetic field on the her, the ph
... The electrodeposition of less noble metals is usually overlapped by the reduction of hydrogen ions. This leads to an increase of the pH value in front of the electrode surface which can result in spontaneous formation of hydroxides. This changes the deposition behaviour, the morphology and the prope ...

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.
