The lab is attached. I've also attached the pre-lab just for the diagram.
The Attempt at a Solution
Can anyone think of some good errors for this lab?
We ended up with ~80% error.
I've thought of two:
1. Adjusting the potentiometer so that the width of the conductor would start with 0 voltage was very difficult.
2. The magnetic field was strongest in the center but was weak on the sides of the wafer. This caused some uncertainty.
