Answer 1

(1A). As the South pole of the magnet is pulled upwards, the direction of the induced current in the coil must be such that, it induces its own magnetic field with its North pole pointing upwards. This is possible by counterclockwise current in the loop (13) From Right hand rule, the induced current in the loop points upwards, with its North pole pointing upwards, as shown in above figure
