P7.2.1.2 Investigating the Anomalous Hall Effect in Tungsten Complete Experiment

Investigating the Anomalous Hall Effect in Tungsten The experiments P7.2.1.1 and P7.2.1.2 determine the Hall coefficient RH of two electrical conductors by measuring the Hall voltage UH for various currents I as a function of the magnetic field B. A negative value is obtained for the Hall coefficient of silver, which indicates that the charge is being transported by electrons. A positive value is found as the Hall coefficient of tungsten. Consequently, the holes are mainly responsible for conduction in this metal.
