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.
