Explanation:
Bar magnet is a permanent magnet.
Bar Magnet has two poles: North pole and South pole.
Same poles repel each other and the opposite poles attract each other.
The magnetic field lines originates from the north pole and ends at the south pole.
The magnetic filed lines are surrounding of the magnet in which the magnetic force can be experienced. The magnetic fields are stronger near the poles of the magnet. As the distances decreases from the poles, the magnetic fields lines get weaker.
Therefore, the correct option is (C).
