Solution

The direction of the magnetic field around a current carrying conductor can be found by Right-hand thumb rule. The magnetic field due to each part of the wire will have a component in the center of the loop that points in one direction.

Using Right-hand thumb rule we can say field line will be towards you, so the part of the loop that faces towards you will be North pole.

Q. There are two loops A and B placed coaxially along vertical line. Loop A is allowed to fall freely towards loop B. If constant current flowing in loop A is as shown in the figure, then find the direction of flow of induced current in loop B as seen from the bottom of loop B.

Q. A permanent bar magnet is moving downward towards a loop of wire as shown in the figure above. Identify the direction of current induced in the wire?

If I keep the north pole of a bar magnet facing a conducting loop and move it towards the loop, I find a current flowing through it, let's say in the clockwise direction. If I want a current to flow in the counter clockwise direction using the same bar magnet, I should :
