the figure shows two concentric conducting rings. If there is a clockwise current I in the larger ring that is decreasing with time, the induced current in tge smaller ring is... A. clockwise B. counter clockwise C. zero

20. Both conducting loops shown below are coplanar (in the y/z axes) and carry current as shown. They are separated by some arbitrary distance. Will they attract or repel each other? current o N current О N A. They will attract each other. B. They will repel each other. C. They will not exert a force on each other. D. They will attract each other and then repel each other as an oscillator.

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

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.
