In the figure below, the cube is 38.4 cm on each edge. Four straight segments of wire-ab, bc, cd, and da-form a closed loop that carries a current / = 4.65 A In the direction shown. A uniform magnetic field of magnitude 8 = 0.019 T Is in the positive y direction. Determine the magnetic force on each segment. (a) ab 0 mN (b) bc F = 0.0339 X mN (c) cd F 0.0332 X mN (d) da F = 0.0335 X mN (e) Explain how you could find the force exerted on the fourth of these segments from the forces on the other three, without further calculation Involving the magnetic field
