(a) In Fig. 28-8, show that the ratio of the Hall electric field magnitude E to the magnitude EC of the electric field responsible for moving charge (the current) along the length of the strip is EEC Bner ,where r is the resistivity of the material and n is the number density of the charge carriers. (b) Compute this ratio numerically for 13. (See Table 26-1.)
