In an experiment designed to measure the Earth's magnetic field using the Hall effect, a copper bar 0.480 cm thick is positioned along an east-west direction. Assume n = 8.46 x 1028 electrons/m3 and the plane of the bar is rotated to be perpendicular to the direction of B. If a current of 8.0o A in the conductor results in a Hall voltage of 5.60 x 10-12 v, what is the magnitude of the Earth's magnetic field at this location?
