From the measurements taken on the above inductor:

  1. If the coupling coefficient was k=1, what would the mutual inductance be?

  2. Estimate the mutual inductance and coupling coefficient of these coils.[1]

  3. Determine which pair of terminals should have the dots (a or b) and (c or d).

2. Submission

Write up a description of your aproach and solution. Submit as a PDF to Blackboard.

1. Don’t expect your calculations to yield One True Number! Use several ways to find M and combine them in a reasonable way to arrive at your estimate.
