Example 4 A conductor, 500 mm long, is moved at a uniform speed at right-angles to its length and to a uniform magnetic eld having a density of 0.4 T. If the e.m.f. generated in the conductor is 2 V and the conductor forms part of a closed circuit having a resistance of 0.5 Q. calculate: (a) the velocity of the conductor in metres per second; (b) the force acting on the conductor in Newtons; (c) the work done in joules when the conductor has moved 600 mm. [10 mls, 0.8 N, 0.43 J]
