Comparison of experimental and theoretical values for the parameter K/t as a function of the separation between the two coils. The theory values are obtained by using the theoretically obtained K and the experimentally measured r. The shaded area represents the spread in the theoretical K/t due to the ~5% uncertainty in Q.
