1.	If it so happens that a diamagnetic subs†an ce hanged from roof with the help of a string and a magnetic field is suddenly switched on,and the diamagnetic subs†an ce jumps out of the field gaining gravitational potential energy,then who does the necessary work against gravity to increase the gravitational potential of the body?
