A) M
B) M/4
C) \[\sqrt{2M}\]
D) M/2
Correct Answer: D
Solution :
Let pole strength of magnet is m. Then, magnetic moment\[M=mL\] ...(i) On cutting the magnet into two parts each of length L/2 (pole strength will be same). So, new magnetic moment \[M'=m\times \frac{L}{2}\] From Eq. (I) \[M'=\frac{M}{2}\]You need to login to perform this action.
