Figure 3 shows a straight wire carrying a current in upward direction. The wire is placed near a wire loop. For each case described below, answer the following questions: a) What is the direction of the magnetic flux through the loop? b) Is the magnitude of the flux through the loop increasing or decreasing with time? c) What is the direction of the magnetic field produced by the induced current in the loop? d) What is the direction of the current induced in the loop? Case 1: The current is increasing. Case 2: The current is decreasing. Case 3: The current is constant but the loop is being pulled away from the straight wire.
