A coil in the shape of an equilateral triangle of side 0.02m is suspended from a vertex such that it is hanging in a vertical plane between the pole pieces of a permanent magnet producing a horizontal magnetic field of 5*10
-2
T. Calculate the couple acting on the coil when a current of 0.1A is passed through it and the magnetic field is parallel to the plane.
