FIGURE 23-8
-A bar magnet with its south pole pointing toward a loop of wire of cross-sectional area 0.020 m² and total number of turns equal to six is stationary near the loop of wire shown in Figure 23-8(a) . What is the direction of the induced emf in that loop of wire (when looking at the end of the coil where the S pole is coming toward you) ?

Since the bar magnet is stationary, there is no change in magnetic flux through the loop, and thus no emf is induced according to Faraday's law of electromagnetic induction.
