Q- A wire frame in the shape of an equilateral triangle of side d = 8 cm, carries current i = 0.25 A. This frame is located in a region of space that contains a constant magnetic field of magnitude B = 1.3 T, Normal to the plane of the frame and the frame is in stable equilibrium. What is the work you would have to do to rotate the frame 180° so that it is again normal to the field?
