(b)(1) Yes, there is
current induced in the solenoid from 8 to A. Jt is because there is change of magnetic flux in the solenoid.
(11)No, there is no
induced current in the solenoid. It is because when the magnet is at its lovest point, it is
instantaneously at rest and there will be no change
of magnetic flux inside the solenoid.
