In the drawing below a wire is looped as shown -- note that the
wire crosses over top of itself with out contacting itself.
The resistance of the wire is 4.3 ohms and the large loop has a
side length of 11 cm, while the smaller loop is half that size. We
assume that the magnetic field starts at a strength of B = 0.5 T
and increases at a rate of 0.24 T/s. If we define current
going clockwise around the top loop as positive, and counter
clockwise as negative, what is the current in the wire in
milli-amps? Give your answer to 3 significant digits.
