A coil in the shape of equilateral triangle of side 0 02 m is suspended from the vertex such that it is hanging in a vertical plane between the pole pieces of a permanent magnet producing a horizontal magnetic field of 5x10 2 T When a current of 0 1 A passes through it and the magnetic field is parallel to its plane then couple acting on the coil is 1 8 65 x 10 7 N m 2 6 65 x 10 7 N m 3 3 35 x 10 7 N m 4 3 91 x 10 7 N m
