| Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). Mark the correct choice as: |
| Assertion [A]: The poles of magnet cannot be separated by breaking into two pieces. |
| Reason (R): The magnetic moment will be reduced to half when a magnet is broken into two equal pieces. |
A) Both Assertion [A] and Reason (R) are true and Reason (R) is the correct explanation of Assertion [A]
B) Both Assertion [A] and Reason (R) are true but Reason (R) is not the correct explanation of Assertion [A]
C) Assertion [A] is true but Reason (R) is false
D) Assertion [A] is false and Reason (R) is also false
Correct Answer: B
Solution :
(b) As we know every atom of a magnet acts as a dipole. So, poles cannot be separated. When magnet is broken into two equal pieces, magnetic moment of each part will be half of the original magnet.
