Answer to Problem 2P
Direction of induced current when north pole of magnet is being inserted into the coil.
Solution:
Explanation of Solution
The induced current flows clockwise when the north pole of magnet is moved towards the coil.
Induced current is set up in the coil because the magnetic flux linked with it changes when the magnet is moved.
According to Lenz’s law, as the induced emf opposes its cause, the induced current flows clockwise and act as north pole and repel north pole of magnet which is being inserted.
Conclusion:
Direction of induced current in a circuit is such that it opposes the cause or the change which produces it.

- 5.97 Block A, with weight 3w, slides down an inclined plane S of slope angle 36.9° at a constant speed while plank B, with weight w, rests on top of A. The plank is attached by a cord to the wall (Fig. P5.97). (a) Draw a diagram of all the forces acting on block A. (b) If the coefficient of kinetic friction is the same between A and B and between S and A, determine its value.
