154071 A bar magnet having a magnetic movement of $2 \times 10^{4} \mathrm{~J} \mathrm{~T}^{-1}$ is free to rotate in a horizontal plane. A horizontal magnetic field $B=6 \times 10^{-4}$ $T$ exists in the space. The work done in taking the magnet slowly from a direction parallel to the field to a direction $60^{\circ}$ from the field is

154072 A bar magnet is hung by a thin cotton thread in a uniform horizontal magnetic field and is in equilibrium state. The energy required to rotate it by $60^{\circ}$ is $\mathrm{W}$. Now the torque required to keep the magnet in this new position is

154073 Following figures show the arrangement of bar magnets is different configurations. Each magnet has magnet dipole moment $M$. Which configuration has highest net magnetic dipole moment ? (i)

154074 A bar magnet of length $I$ and magnetic dipole moment $M$ is bent in the form of an arc as shown in figure. The new magnetic dipole moment will be
