A metal strip 650 cm long 0850 cm wide and 0760 mm thick mov

A metal strip 6.50 cm long, 0.850 cm wide, and 0.760 mm thick moves with constant velocity v through a uniform magnetic field B = 1.20 mT directed perpendicular to the strip as shown below: A potential difference of 3.34 mu ? is measured between the points x and y across the strip. Calculate the speed v.

Induced emf = B d v

3.34 x 10^-6 = (1.20 x 10^-3) ( 0.850 x 10^-2) (v)
