Physics EE help

Recommended Posts


I have decided to write my EE in physics. I am going to investigate electric guitar pickups and I need help adding more 'depth' to the essay.

Currently, I plan to create my own model pickup by winding a coil of enamel coated copper wire around it, and seeing how it picks up sound from a vibrating string. I will be changing the amount of turns on the coil, as well as the cross sectional area of the coil to see how it affects the induced current. I also plan to experiment with how the position of the pickup along a string (on a sonometer, that is) affects the output.

The topic question i have so far, is: How does pickup winding and pickup position along a string affect the tone and timbre of the signal? I am worried that there won't be enough to write about on a high school level. I plan to analyze the tone by looking at different frequency levels and harmonics in the signal, but I feel I need more physics in this physics essay, if that makes sense. Is this a good topic? What do you think i could expand on, or analyze more to create a better, and more scientific essay?

Thank you.
