Learn how to measure the Hall voltage, resistance and conductivity of chromium and silver samples in a magnetic field. Find the Hall coefficient, charge density and velocity of electrons and verify the sign of charge carriers.
In 1879, E.H. Hall devised an experiment that can be used to identify the sign of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.
15 kwi 2010 · The basic physical principle underlying the Hall effect is the Lorentz force, which is a combination of two separate forces: the electric force and the magnetic force. When an electron moves along the electric field direction perpendicular to an applied magnetic field, it experiences a magnetic force - q v X B acting normal to both directions.
