Q. A current carrying loop is free to turn in a uniform magnetic field. The loop will them come into equilibrium when its plane is inclined at
A) $0{^\circ}$ to the direction of the field
B) $45{^\circ}$ to the direction of the field
C) $90{^\circ}$ to the direction of the field
D) $135{^\circ}$ to the direction of the field
Explanation
(c) In equilibrium angle between $\overrightarrow{M}$ and $\overrightarrow{B}$ is zero. It happens when plane of the coil is perpendicular to $\overrightarrow{B}$
