Question:

A long copper strip 1.8 cm wide and 1.0 mm thick is placed in a 1.2-T magnetic field as in Fig. 20-21a. When a steady current of 15 A passes through it, the Hall emf is measured to be 1.02 μV. Determine

(a) The drift velocity of the electrons

(b) The density of free (conducting) electrons (number per unit volume) in the copper.
