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 4.7 ohms and the large loop has a side length of 19 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 0.27 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.

À rectangular loop of wire is placed next to a straight wire, as shown in figure below. There is a current of 4.3 A in both wires. Take a = 6.0 cm, b = 11.0 cm and c = 3.0 cm. Determine %3D the magnitude and direction of the net force on the loop. (Choose toward wire direction as the positive and express the direction of the net force by using plus or minus signs in the result, which must be in multiples of 10 6 Newtons and includes 2 digit after the decimal point. That means if you get a result of a 9.22 x 10 6 and the direction of the net force is toward the wire, just type 9.22 or if you find the direction of the net force as opposite to the wire, just type -9.22 in the answer box.
