The four wires shown in the figure below all carry the same current from point A to point B through the same magnetic field (the blue lines show the direction of the magnetic field ). The points A and B are 10 cm apart. Rank the wires according to the magnitude of the magnetic force exerted on them, from greatest to least
Select one:
(a), (b) = (c), (d)
(a), (d), (b) = (c)
(d), (a), (b) = (c)
