Vedclass · Answer

(B) The magnetic moment is a vector quantity directed from the South pole to the North pole.When two identical magnets of magnetic moment $M$ are placed perpendicular to each other,their magnetic moment vectors $\vec{M_1}$ and $\vec{M_2}$ are also perpendicular.The resultant magnetic moment $M^{\prime}$ is given by the vector sum:$M^{\prime} = \sqrt{M_1^2 + M_2^2 + 2M_1M_2 \cos(90^{\circ})}$Since $M_1 = M_2 = M$ and $\cos(90^{\circ}) = 0$,we get:$M^{\prime} = \sqrt{M^2 + M^2} = M\sqrt{2}$Given that the magnetic moment $M = ml$,we substitute this into the expression:$M^{\prime} = ml\sqrt{2}$

If two identical bar magnets,each of length $l$,pole strength $m$ and magnetic moment $M$ are placed perpendicular to each other with their unlike poles in contact,the magnetic moment of the combination is
