2. A circular loop consisting of a single turn of wire and a diameter of 15 cm lays flat at the edge of a table, as shown. A uniform magnetic field of 0.50 T passes perpendicularly through the table and nowhere else. If the loop is pulled horizontally straight off the table at a speed of 15 m/s, what is the average emf induced in the loop. In what direction does the resulting induced current flow? If the loop has a resistance of 10 , how much current is induced in the loop? Hint: this is NOT motional emf problem. [Answers: (a) & = 0.88 V, (b) ccw, (c) I = 0.088 A] 0 0
QUESTION 23 In generating electricity, a magnet, surrounded by wires connected to the electrical grid, will be made to spin, using wind, a steam turbine, or moving water. Which answer best explains what is happening in the wires during this process. a. The magnet does not need to move, and still has the capability to make electrons move in the wires that surround it. b. An induced voltage and current flow is set up in the wires surrounding a magnet due to changes in magnetic temperature. c. A magnetic field surrounds the rotating magnet, pushes on the electrons in the wires, thus giving those electrons energy per charge (voltage). d. Light from the magnet is able to push electrons out of the material that makes up the wires. In so doing, the wires are made to have a flowing electrical current.
