Hall Effect Apparatus

The Hall Effect Apparatus explores solid-state physics and conduction phenomena.

All Major Components Included
Two Material Options: Silver and Tungsten
Apparatus Explores Solid-State Physics and Conduction Phenomena
Hall Coefficient Determined by Measuring Hall Voltage UH for Various Currents
Negative Value Indicates Electrons Are Transporting Voltage

Users 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.
