Question

From the figure given below, choose the points where the net magnetic field induction is zero.

• A. B
• B. C
• C. A
• D. D

Answer 1

The correct option is C

A

1. The neutral point of the magnet is where the resultant magnetic field is zero.
2. In the magnet, magnetic field lines emerge from the north pole.
3. We can see that the neutral point is between both the magnets as both magnets are facing the north pole and there is no attraction between them.
4. So, net magnetic field induction is zero at point A.
5. Hence, the point where the net magnetic field induction is zero is A.

The correct option is (C).
