Hall effect, illustration

| Hall effect. Illustration of a germanium Hall effect wafer (upper left) and the resulting Hall effect in the germanium crystal (bottom right). An electrical current (pink line) is applied to the crystal and a potentiometer (ring at far right of Hall effect board) is used to balance the voltage to zero. The wafer is placed in a magnetic field perpendicular to the direction of the current. This causes a deflection in the current that leads to a negative charge building up on one side of the crystal, with a positive charge on the opposite side, and thus an electric potential is induced. This potential difference is called the Hall voltage. | |
