The magnetic field through a single loop of wire 12.0 cm in radius and of 7.5 Ω resistance changes with time as shown in the figure. Calculate the emf in the loop as a function of time.What is the emf at t = 1.0 s? For the sign take the loop in the plane of the paper, and the magnetic field out of the paper. Take clockwise to be positive emf.  What is the emf at t = 3.0 s?  What is the emf at t = 5.0 s?  What is the current at t = 1.0 s?

A rectangular coil of wire, 22.0 cm by 35.0cm and carrying a current of 1.95A, is oriented with the plane of its loop perpendicular to a uniform 1.50-T magnetic field (Figure 1). a) Calculate the net force that the magnetic field exerts on the coil. Express your answer with the appropriate units. b) Calculate the torque that the magnetic field exerts on the coil. Express your answer with the appropriate units. c) The coil is rotated through a 30.0 degree angle about the axis shown, with the left side coming out of the plane of the figure and the right side going into the plane. Calculate the net force that the magnetic field now exerts on the coil. (Hint: In order to help visualize this three-dimensional problem, make a careful drawing of the coil when viewed along the rotation axis.) d) Calculate the torque that the magnetic field now exerts on the coil.
