Question

1. The permeability constant for a vacuum is ų0, has a value of 4(pi)×10-7 Tm/A. Assuming the equation B=ų0nI applies to the Slinky, obtain a value of (pi) from your graphs, and compare with the 'theoretical' value.

 

2. Was your Slinky positioned along an east-west, north-south, or on some other axis? Will this have any effect on your readings?
