Question
A bar magnet is held above a circular loop of wire as shown in the figure (Figure 1) . The plane of the loop is perpendicular to the page.
Find the direction (clockwise or counterclockwise, as viewed from below the loop) of the current induced in this loop if the loop is dropped.
answer: clockwise
can someone explain why the answer would be clockwise? I thought the magnetic field of the magnet was pointing up so if the loop was dropped then the current would move counterclockwise to compensate for the reduced flux? what am i missing here

Because the direction of the induced current has to in such a way that it opposes the cause of it.(Lenz's law)Now a south pole goes far from the loop so there has to be a north pole there to attract and take back the loop to the previous position.For a north magnetic pole to be existent there the current has to flow in clockwise direction when seen from bottom . The direction of field is given by right hand rule.
