magnetic -14 A metal strip 6.50 cm long, t force. 0.850 cm wide, and 0.760 mm thick moves with constant velocity V igh po- through a uniform magnetic field B X X B paral- 1.20 mT directed perpendicular to the strip, as shown in Fig. 28-34. A poten- erence tial difference of 3.90 / V is measured X between points x and y across the strip. Calculate the speed v.
