A flat copper ribbon 0.330 mm thick carries a steady current of 44.0 A and is located in a uniform 1.60 T magnetic field directed perpendicular to the plane of the ribbon. If a Hall voltage of 9.60 µV is measured across the ribbon, what is the charge density of the free electrons? 1.38E29 What effective number of free electrons per atom does this result indicate?
