Hall effectA current of 9 mA is passed through a bar of silicon while a magnetic field of 14870 Gauss is applied perpendicular to the current flow. The cross section of the bar is 0.004 cm². Two voltage probes are placed a distance 626 μm apart in a direction perpendicular to both the current flow and the magnetic field. The voltage that is measured is -5 mV. 1 Tesla = 1 Weber/m² = 10-4 Weber/cm² = 104 Gauss |
