Question

Two identical magnets are kept one over the
other with their like poles together. The
resultant magnetic moment of combination will
be :
A) M1 + M2
B) M1 - M2
C) 2M
D) zero​

Answer 1

Answer:

ans for this is A.M1+M2

Answer 2

The resultant magnetic moment of combination will be $\sqrt{3}M$

Explanation: Given, Two identical magnets are kept one over the other with their like poles together.

We know, the resultant magnetic moment

$\Rightarrow M_{res}=\sqrt{M^{2}_{1}+ M^{2}_{2}+M_1M_2cos\theta$

The magnets are kept over one another with like poles together.

$\therefore \theta = 0\° \Rightarrow cos\theta =cos 0\°=1$

As magnets are identical, $M_1=M_2=M$

$\Rightarrow M_{res}=\sqrt{M^2+M^2+M^2}=\sqrt{3}M$
