A Hall-effect probe operates with a 120 -mA current. When the probe is placed in a uniform magnetic field of magnitude 0.0840 T, it produces a Hall voltage of 0.660 µV. The thickness of the probe in the direction of B is 2.00 mm. Find the density of the charge carriers, each of which has charge of magnitude e).
I am using Vh = IB/net, where i can get the value for n.
the value of n is electrons/m^3
but the answer should be in m^-3.
Thank you
