Calculate the value of the Hall emf that occurs when a current of 100 mA is passed through a plate of sodium metal in a field of 0.1 Tesla. The width of the sample along which the Hall voltage is measured and perpendicular to which the magnetic field is applied is equal to l = 1 mm. The Na lattice is a body-centered cube with a side of 4.28 A.
