United Scientific Supplies Hall Effect Apparatus

Description

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 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 and is associated with several well-known systematic errors, some of which can be eliminated by 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.
• Explores the Hall Effect in a GaAs semiconductor.
• Explores systematic errors and their elimination. Determines the conductivity of the semiconductor.
• Uses the semiconductor to plot the coils' magnetic field. n-type GaAs Hall sensor chip.
• Helmholtz coil pair 75 mm effective diameter, 11.25 mT central magnetic induction at 0.5 A.
• Two-axis mechanical traverse for field plotting.
• Constant current sources for magnet (0-0.5 A) and Hall driving current (0—3 mA).
• 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.
