If the ammeter a shows a zero reading
WebSolutions. ( 1) As the magnet is inserted into the coil, there is a change in magnetic flux linkage. The magnetic flux linkage in the coil increases because the magnetic field increases. When the bar magnet is completely inside the coil, the magnetic field becomes constant and the current induced is zero. Hence, option (B) is correct.
