A rectangular frame axb lies in the same plane with a straight conductor through which current I flows, and which is located parallel to side b, at a distance d > a from the nearest side (figure). What charge Q will pass through the cross-section of the wire of the frame if it turns around the side b closest to the wire at an angle n and remains in this position? Frame wire cross-section S, resistivity p. Neglect the self-induction of the frame.
