We measure voltage difference as we move the magnet

This preview shows page 1 - 3 out of 5 pages.

We measure voltage difference as we move the magnet in the coil. Voltage should go up where near the magnet’s south pole. Thus as the north pole is moved into the coil, voltage goes down. So the side with the black tape is the south pole of a magnet 4. From the data you collected, what was the maximum induced current, NOP, in your coil? ? What determines the value of the current? Hint: The coil has a resistance of 150Ω. max = 1.134V Min = -1.219V V=2.263V Resistance 150 ohms imax= 2.263V/150ohm=0.015A 5. Describe the shape of the waveform in the secondary coil for a sine, square and triangle wave in the primary coil. How does the signal in the secondary coil relate to the one in the primary coil? The signal in the secondary coil is the first derivative of the first. 6. How does the slope of the input waveform relate to the induced emf? They are the same. 7. Are the induced emf and applied voltage waveforms in phase? That is, do the peaks and valleys of the two waveforms line up? Why or why not?

They are in phase. The peaks do not line up because the second one is the derivatives of the first. 8. Submit the plots you created in step 4. How do the variables E5,NOP and 5 relate to the ? induced voltage E6,NOP and 6? ?

    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.
