Question
In the sketch (not to scale) a long straight wire carries a current I_1, upward n the plane of the page A square wire loop is also in the plane of the page and to the right of the straight wire. It carries a counterclockwise current of I_2 and its side is parallel to the wire. Which of the following statements correctly describes the net force on the frame of wire: A) The net torque on the wire frame attempts to rotate counterclockwise. B) The net force on the wire frame is zero, but the net torque attempts to rotate it around a horizontal axis. C) The net force and torque on the wire frame are both zero. D) The frame is repelled by the wire. E) The frame is attracted to the wire.Explanation / Answer
Ans is frame is attracted to the wire.(option E)
since B is larger as one gets closer to the wire
no torque between strainght wire and loop because they are in same plane
