Question

The figure shows two diamagnetic spheres locate near the South Pole of a bar magnet. Then

Answer 1

Since spheres $1$ and $2$ are diamagnetic, so force $\overrightarrow{F_1}$ and $\overrightarrow{F_2}$ on both the spheres will be in opposite direction to the external field


Suppose the dipole moment for sphere be $M$.


$\because F_{-m}>F_{+M}\Rightarrow F_{net}$ towards right

$\therefore$ Magnetic dipole moment of sphere $2$ is towards right.

Hence, $\left(B\right)$ and $\left(D\right)$ are correct options.
