The figure below shows a long straight wire with current i to the right and three wire loops. The loop all have the same clockwise current i̟ flowing around them. The upper edges are all at the same distance D from the long wire and the loops all have edge lengths of either L or 2L. b. a The straight wire will be our source and it creates a magnetic field, given by the results from Ampere's law (you can look up the equation for the magnetic field outside of a long straight wire in the text or your notes, I am not asking you to re-derive it but rather to use it here.) This field of the straight wire exerts a net force on each loop. (a) Draw a diagram showing the direction of the magnetic field at and the forces on each segment of each loop.

(b) Rank the loops according to the magnitude of the NET force exerted on each loop, greatest
first. Explain your answer.
(c) Find an expression (in terms of i, iL, L and D) for the net force exerted by the straight current
i on loop a (the square loop with sides length 2L) and determine its direction.
