Question
In the figure below, a long straight wire with a current i passes through three rectangular loops. Loop 1 has edge lengths L by 2L. Loop 2 has edge lengths L by 1.5L. Loop 3 has edge lengths L by L. Loops 1 and 3 are symmetric about the straight wire. The loops are widely spaced so that they do not affect one another. Rank the loops according to the magnitude of the induced emf in them if the current i is increasing at a constant rate, greatest first.
