mT A Hall-effect probe operates with a 120 -mA current. When the probe is placed in a uniform magnetic field of magnitude 0.0880 T, it produces a Hall voltage of 0.800 μV. (a) When it is used to measure an unknown magnetic field, the Hall voltage is 0.320 μV. What is the magnitude of the unknown field? M-3 (b) The thickness of the probe in the direction of B is 1.80 mm. Find the density of the charge carriers, each of which has charge of magnitude e).
