1. The problem statement, all variables and given/known data The lab is attached. I've also attached the pre-lab just for the diagram. 2. Relevant equations 3. 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.
