Hint:
Magnetic lines of force is one kind of hypothetical line in which the force of the magnet can be detected. This region is also known as the magnetic field. If a bar magnet intersects then two directions of magnetic field intensity are found but that is actually impossible.
Complete step by step solution:
Magnetic lines of force or flux are invisible lines that connect the north and south poles of a magnet. In a simple bar magnet, these lines flow from the south pole to the north pole. If you cut a bar magnet in half, you will see that the lines of force continue through the magnet, with half of them on each side of the cut.
You can see the magnetic lines of force effect in a number of ways. One is to sprinkle iron filings on a sheet of paper and put the magnet underneath. The filings will line up along the lines of force. You can also see the effect of the lines of force by using a compass. If you move the compass near a magnet, the compass needle will move and point in the direction of the north pole of the magnet.
Now let’s find out the reason why magnetic field lines do not intersect.
Magnetic lines of force due to a bar magnet do not intersect because there are two directions at same time which is not possible.
Hence our answer is that the point has a single net magnetic field.
Therefore, the correct option is A.
Note:
When the distance increases between poles, the density of magnetic lines also decreases. If we consider a magnet as a magnetic dipole with its south pole and north pole by a specific distance but with increasing distance there arises at a certain point where the magnetic field also decreases.
