In each case, a long, straight wire is placed next to a circular wire loop that has a small light bulb in it. The currents in the long wires are changing at uniform rates. The initial current, the final current, and the time interval during which the change occurs are given. The bulbs and wire loops are all identical, and the straight wires are all the same distance from the wire loops. Rank the bulb brightness (greatest to least) during the time that the current changes. Explain your reasoning
