Two circular loops are parallel, coaxial, and almost in
Chapter 19, Problem 19.58(choose chapter or problem)
Two circular loops are parallel, coaxial, and almost in contact 1.00 mm apart (Fig. P19.58). Each loop is 10.0 cm in radius. The top loop carries a clockwise current of 140 A. The bottom loop carries a counterclockwise current of 140 A. (a) Calculate the magnetic force that the bottom loop exerts on the top loop. (b) The upper loop has a mass of 0.021 0 kg. Calculate its acceleration, assuming that the only forces acting on it are the force in part (a) and its weight. [Hint: The distance between the loops is small in comparison to their radius of curvature, so the loops may be treated as long, straight parallel wires.]
