Before revision: Having completed the measurements, a negative magnetic field is applied in place of the positive one, and the above procedure is repeated to obtain the voltage measurements V13, N, V42, N, V31, N and V24, N. Calculations First of all , the difference of the voltages for positives and negative magnetic fields needs to be worked out : V13 = V13, P − V13, N V24 = V24, P − V24, N V31 = V31, P − V31, N V42 = V42, P − V42, N The overall Hall voltage is then .
