Chapter 28, Problem 014 A metal strip 8.09 cm long, 1.10 cm wide, and 1.11 mm thick moves with constant velocity through a uniform magnetic field B = 1.09 mT directed perpendicular to the strip, as shown in the figure. A potential difference of 5.34 is measured between points x and y across the strip. Calculate the speed v.

Explanation / Answer

induced emf = B L v

e = B L v

where L is dimesnion pependiculat to the v and B.

L = 1.10 cm = 0.011 m

5.34 x 10^-6 Volt = (1.09 x 10^-3 T) (0.011 m) (v)

v = 0.445 m/s
