About This Product
The Hall effect is the side-to-side voltage that appears in a conductor or semiconductor carrying a current when it is placed in a magnetic field. With this set the effect is studied in a GaAs semiconductor, the conductivity of the semiconductor is found, and the chip is used to plot the magnetic field of the coils. The reversing switches let several well-known systematic errors be explored and removed. Science Lab Export can supply the Hall Effect Apparatus to Lithuania, Brunei, Laos, Benin and Madagascar.
