Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 7A A U-shaped wire is connected across its open end by a conducting bar that is being pulled with constant speed v = 1.0 m/s away from the bottom. A magnetic field with magnitude B = 12 mT is directed perpendicular to the circuit. The width of the “U” is L = 30 cm and the resistance of the entire circuit is 90 mΩ at present. a) Calculate the value of the current induced in the wire. b) Calculate the value of the force felt by the bar as a result of the induced current in it. What is the direction (toward the bottom or top of the “U”) of the force?
