A strip of copper is placed in a uniform magnetic field of magnitude 2.5 T. The Hall electric field is measured to be 1.5 × 10−3 V/m. (a) What is the drift speed of the conduction electrons? (b) Assuming that n = 8.0 × 1028 electrons per cubic meter and that the cross-sectional area of the strip is 5.0 × 10−6 m2, calculate the current in the strip. (c) What is the Hall coefficient 1/nq?
