Question

Two bar magnets are placed on a horizontal surface. Draw magnetic lines around them. Mark the position of any neutral points (points where there is no resultant magnetic field) on your diagram.

Answer 1

Hint: This is the question based on the concept of the neutral point in the case of the bar magnets. We know that a neutral point is a place where the resultant magnetic field is zero, that is, the place where there are no magnetic lines of force present. So, we will draw the same by placing the bar magnets on the horizontal plane.

Complete step by step answer:
The neutralized region in the case of the magnetic field is the place where no flow of the magnetic lines of the force takes place. This is because; the magnetic field is produced by the flow/presence of magnetic lines of force. A point where the horizontal components of the earth’s magnetic field neutralize the field due to the magnet is called the neutral point.
The diagram represents the magnetic lines around two bar magnets placed on a horizontal surface and the position of a neutral point is as shown below.

In this diagram, the north poles of both the bar magnets are placed side by side. The reason being, the like charges, that is, the north poles or the south poles of the magnets repel each other and the, unlike charges, that is, the north poles and the south poles of the magnets attract each other.

This should be the arrangement of the bar magnets to obtain the neutralized region (that is, the neutral point) in the magnetic field produced by these bar magnets.
The magnetic lines of force emerging out from the north poles of both the bar magnets placed on the horizontal plane cancel out each other, thus, making that region neutralized.
Therefore, the diagram representing the magnetic lines around two bar magnets placed on a horizontal surface and the position of a neutral point is drawn.

Note:
If the magnet placed on a horizontal plane is rotated by some angle, then, the neutral point, that is, the region in the magnetic field produced by the bar magnet where there is no magnetic field will rotate by half the angle by which the magnet is rotated.
