The rectangular coil shown below has 15 tuns and carmies a cunent /= 6.5A in the lirection as indicated in the figure. It is located in a uniform magnetic ficeld of B= 0.5T 9. The dimensions and orientation of the coil is h= 75 cm, w = 4.0 cm and 0- 35.0. %3D a) What is the magnetic dipole moment ji of the coil? Express it in terms of £, 9, 2 unit vectors. b) At this orientation, calculate the torque 7 acting on the coil. If the coil is free to rotate around the z-axis, based on the direction of 7, which direction does this torque attempt to rotate the coil (CW or CCW looking down from the +z-direction)? c) How much work is required to rotate the coil so that the B-field lies in the plane of the coil?
