Consider again the long wire near a small wire rectangle. The long wire is part of a circuit. The circuit is small enough that all the approximations we've used in class are good, but the wire near the rectangle is much longer than the rectangle. The dimensions are those you have used before: c is the distance from the long wire to the side of the rectangle parallel to the long wire; b is the length of the rectangle parallel to the long wire; a is the remaining dimension of the rectangle.

1. Calculate the mutual inductance M of the two circuits (the rectangle and the circuit containing the long wire).
2. What is the value of M in Henrys if a = 2:0 cm, b = 5:0 cm and c = 3:0 cm?
