A current carrying coil placed in a magnetic field B experiences a torque \\tau. If \\theta is the angle between the normal to the plane of the coil and field {B} and \\phi is the flux linked with the coil, then

Correct Answer is : τ is zero and φ is maximum for θ=0°

\\tau is minimum for \\theta=90^\circ

\\tau and \\phi are maximum for \\theta=0^\circ

\\phi is maximum for \\theta=90^\circ

\\tau and \\phi are zero for \\theta=90^\circ

\\tau is zero and \\phi is maximum for \\theta=0^\circ
