25. A long, straight wire is in the same plane as a rectangular, conducting loop. The wire carries a constant current I as shown in the figure. Which one of the following statements is true? A. There will be no induced current. B. There will be a clockwise induced current in the loop. C. There will be a counterclockwise induced current in the loop.

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.

When you push the South end of a magnet into a solenoid, it creates a negative voltage. If you push the North end of a magnet into the solenoid, it will create A. no voltage B. a negative voltage C. a positive voltage D. a capacitor

12. The current in a long solenoid of radius R and n number of turns per unit length is increasing linearly with respect to time, where I = at. Two ideal voltmeters are connected across two resistors (R, and R₂) that will measure induced voltage in a square coil of length L. V₁ R₁ b Solenoid a R₂ V₂ a. Determine the flux through the solenoid as a function of time. b. Determine the magnitudo ond
