Hall effect lab report
WebJul 12, 2024 · The Hall effect is the measurable voltage through a conductor (or semiconductor) when an electric current flowing through it is influenced by a magnetic field. In these conditions, a transverse voltage is generated perpendicularly to the applied current because of the balancing of the Lorentz (electromagnetic) and electric forces. WebNov 24, 2015 · This report presents a series of experiments for studying the conduction properties of semiconductors. The results are analyzed using the relevant theory to determine the parameters of conduction. Several Conduction theories will be explored in order to better understand the experiment.
