D3-SCT31: MOVING MAGNET AND CIRCULAR LOOP-FORCE Three students are comparing the forces on a permanent magnet and a current-carrying circular loop of wire. The mass of the magnet is much larger than the mass of the loop. V- 4 m/s N Amador: "The coil will push or pull on the magnet just as hard as the magnet pushes or pulls on the coil." Barbara: "I think the magnet has to push harder on the coil than the coil pushes on the magnet because the magnet is more massive than the wire." Charlene: "I think the magnet will push or pull on the coil but the coil will not push or pull on the magnet at all because the coil is not a magnet." With which of these students do you agree? Amador Barbara Charlene None of them, Explain your reasoning.
