A coil in the shape of an equilateral triangle of side 0.02 m 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 5×10−2T. Find the couple acting on the coil when a current of 0.1 A is passed through it and the magnetic field is parallel to its plane.

Figure shows a short magnet executing small oscillations in an oscillation magnetometer in earth’s magnetic field having horizontal component 24μT. The time period of oscillation is 0.10s. An upward electric current of 18A is established in the vertical wire placed 20cm east of the magnet by closing the switch S. Find the new time
