A current-carrying coil of magnetic moment `vecM` is placed in a uniform magnetic field of induction `vecB` such that the angle between `vecM` and `vecB` is `30^(@)`. If `M=5 A.m^(2)` and `B=0.2 Wb//m^(2)`, what is the torque acting on the coil?

Explanation

The torque acting on the coil, `tau = Mbsintheta = (5)(0.2)(0.5) = 0.5 N-m`
