Now if you take the north pole of magnet away from conducting loop....current will now flow in clockwise direction i.e. south pole get induced in loop.....why south pole??because as you take magnet away from loop current in circuit decreases ...so now it tries to oppose this effect i.e.tries to increase current in loop and induces south pole to attract the magnet.....

Lenz law states that direction of induced emf is such that it opposes the cause which produce it......means direction of emf will be such so as to reduce the effect that is inducing it ......for eg......you are bringing a north pole of magnet towards a conducting loop...now in conducting loop current will get induced in north direction (anticlockwise) as seen from side of magnet....now why north direction??because north will repel north pole of magnet and will try to reduce its effect....

ANSWER

A magnet is given in a diagram....its north pole pointing in downward direction....and an arrow pointed towards down side......an metal ring is placed below it. Now question is in which direction the induces current will flow ?

VB- ( valancy creator means electron movement starts gaining thermal energy)?overcome energy bandgap ?enter into CB - ( electron reach there) ,,,,,,it's like we are going from class 9th to 11th ( 10th as energy band gap without doing this we cannot be promoted to 11th from 9th) as class 9th is lower( energy level) than 11th
