The expression for the induced emf is, ε=-dφdt Refer the graph, the graph implies that rate of change of magnetic flux. For the flux has the maximum negative slope, there will be maximum positive emf and vice- versa. At point A, the slope is negative, so emf at point A is positive. At point B and D, the slope is zero, so emf is zero. At point C, slope is positive, so emf is negative. At point E, the slope is more negative than that of point A. So, emf is more positive at point E than that of point A. Hence, the required ranking is, E>A>B=D>C

Suppose that the light bulb in Figure 22.4b is a 60.0-W bulb with a resistance of 210 Ω. The magnetic field has a magnitude of 0.247 T, and the length of the rod is 1.30 m. The only resistance in the circuit is that due to the bulb. What is the shortest distance along the rails that the rod would have to slide for the bulb to remain lit for one-half second?
