Question

A compass is placed between two magnets of equal magnetic strength as shown in the diagram. In which direction will the compass needle point?

Answer 1

Hint: In order to solve this question we should be aware of the magnetic field lines obtained from the two bar magnets placed side by side each other and observe the field lines which are emits from both bar magnets.

Complete step by step answer:

-The above diagram which shows the magnetic field lines created by the two closely separated north poles of a bar magnet. When opposite poles of two magnets are brought together because like poles repel each other, the magnetic field lines join together and become denser between the poles.
-If we place the magnetic compass in between the two bar magnets it shows zero deflection because the compass needle shows earth magnetic direction. Because in between the magnetic field line due to bar magnetic, the field lines cancel out each other.

Hence the compass needle shows zero deflection.

Additional information:
The compass needle itself behaves as a magnet. When we take the compass needle towards the bar magnet, it points towards the north. Hence, we can conclude that the north point of a compass is attracted towards the south end of the magnet.

Note: Magnetic compass works on the directive property of a magnet. Its needle is magnetic and allowed to rotate in a horizontal plane. One end of the needle always point north and is painted red. It is used for navigation purposes.
