For case (a). what is the induced current? C. For case (a), what is the direction of the current? a. clockwise b. counterclockwise c. no current  c.  no current

6. Two moving rods of equal lengths (1.30 m) are moving as shown in the figure. The speed v₁ = 1.10 m/s and the speed V₂ = 1.40 m/s. If the magnetic field is uniform with a magnitude of 0.90 T, what is the magnitude of the average emf in the loop? What is the direction of the induced current in the circuit? O V Counterclockwise None of these Clockwise

Two coils are connected to different power supplies. Each coil carries a current of 0.15 A. Coil A has 300 turns of wire. Coil B has 400 turns of wire. Which of these statements is correct? Select one: a. Coil B produces a larger magnetic field because it has more resistance. b. Coil B produces a larger magnetic field because it has more turns. c. Coil A produces a larger magnetic field because it has less resistance. d. Coil A produces a larger magnetic field because it has fewer turns of wire.

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.
