The bars did fall as expected. When the iron bar was dropped through the copper pipe, it came out to the other side right away while when the magnet was dropped, it took longer until it came out the other way. This relates to the laws of induction, particularly Lenz’s law, because while the magnet was falling through the copper pipe, it was conducting electric currents that was opposing the change that it induces therefore increasing the time it takes for the magnet to come out to the other end of the pipe. 2. (1 pt; Sect. 4) As before, move the same end of the magnet in and out of the solenoid, but this time do so more quickly. Does this change the sign and magnitude of the peak voltage? Justify this with plots and explain the difference using the theory of experiment. Moving the same end of the magnet in and out of the solenoid quickly did not change the sign of the peak voltage however it did change the magnitude. Since the magnet is moving faster, the magnitude of the peak voltage increased but it remained the same sign. Since the magnet is moving faster, this will create a greater electric current to oppose the greater change induced through the faster moving magnet. 3. (1 pt; Sect. 4) How does the response of the secondary solenoid differ for the two different signals in the primary solenoid? For the square wave what is the behavior of the secondary solenoid when the applied voltage is constant in the primary one? Show your results with plots and justify them by explaining the relationship between the two signals. Explicitly, how does the secondary voltage relate to the applied voltage in the primary? 4. (.5 pt; Sect. 6) How does the magnitude of the induced voltage compare to the previous observations made with the iron core represent; is the magnitude greater or smaller? Explain what characteristic of the iron core could cause such difference.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
