United Scientific Hall Effect Apparatus

By: United Scientific Item#: 1598725
Explore the Hall Effect in a GaAs semiconductor; Explore systematic errors and their elimination; Determine the conductivity of the semiconductor; Use the semiconductor to plot the coils’ magnetic field

The Hall Effect is the generation of a side-to-side voltage in a conductor or semiconductor carrying a current when it is placed in a magnetic field. The effect is widely used in magnetic field sensors. It is associated with several well-known systematic errors, some of which can be eliminated by special measurement techniques.

This Hall Effect Apparatus consists of a mounted n-type semiconductor chip on a traverse mechanism, a pair of coils, relay-controlled reversing switches, and a control unit with connecting cords.

Features:

n-type GaAs Hall sensor chip

Helmholtz coil pair 75mm effective diameter, 11.25mT central mag-netic induction at 0.5A

Two-axis mechanical traverse for field plotting

Constant current sources for magnet (0-0.5A) and Hall driving current (0—3mA)

Reversing switch for exploring the elimination of systematic error

3-1/2 digit current and voltage meters

Metal storage case for the Hall Effect board
