Hall Effect Setup
Hall Effect Setup
If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers, which tends to push them to one side of the conductor, producing a measurable voltage between two sides of the conductor, this voltage is Hall Voltage. Through Hall Effect Setup we can determine carrier density, the mobility of charge carrier, Hall coefficient, Hall voltage etc. We can study the effect of temperature in semiconductor, relation between magnetic field and Hall voltage.
