Experimental determination of Hall co-efficient



In the experimental determination of Hall coefficient, a thin metallic strip of several mm wide and several cm long in the x-direction is placed in a magnetic field H in the Z-direction as shown in  Fig. 14.  A suitable current is allowed to flow in the specimen along x-direction which can be subjected to a variable rheostat. Two potential leads are placed between the points A and B which are connected to a sensitive calibrated potentiometer.  Thus, the Hall voltage is measured with the help of calibrated potentiometer.  It ranges from 0.1 to tens of micro volts in typical case so that stray potentials due to thermal effects create difficulty in these measurements. Measuring the Hall voltage, Hall coefficient can be calculated. Ey which is given by
