Unformatted text preview: the loop normal to a line connecting the poles. The magnetic field in the area of the loop is 0.80 T. (a) What is the peak emf generated if the plane of the wire loop is rotated at 600 rpm? (5 points) (b) Assume that the wire has a resistance of 0.10 ohms/m and that the wire loop forms a circle. What is the maximum current through the loop when it is rotated at 600 rpm? (5 points) (c) What are the peak and average electrical power dissipations when the loop is rotated at 600 rpm? (3 points each) (d) A small cut is made in the loop and a 5 ohm resistor is placed in series with the loop to bridge the cut. How much mechanical energy is required to turn the loop at 600 rpm for 10 seconds? (9 points)...
