A bar magnet is pulling through a stationary conducting loop of wire along the axis of the loop and at a constant speed, as shown in the figure 3. Ne b) Figure 3: A bar magnet pulling through a conducting loop a) Describe qualitatively the change in magnetic flux through the loop when the bar magnet is above and below the loop. State the direction of the induced current in the loop while the bar magnet is approaching the loop. Justify your answer. c) State the direction of the induced current long time after the magnet bar is at centre of the loop.
