Wire A lies a distance d = 0.180 m to the left of a square loop with sides L = 0.453 m in length, as shown in the figure below. The loop carries a current of I = 0.422 A in the direction indicated. Another long, straight wire, which we shall call Wire B, carries a current of IB = 0.817 A. Wire B lies distance d = 0.180 m to the right of the square loop, as shown below.

- Two identical conducting bars of length 56.6 cm can be moved across two parallel conducting wires. The bars can be moved either to the left or right with the speeds v₁ and v₂. The top wire has a resistor with a resistance of 3.2 and the bottom wire has an ammeter (a device used to measure the current). The ammeter has neglibible resistance and reports a positive current if the current flows through it to the right.
