A magnet is dropped through a copper pipe. The magnet falls slower than a pencil that was dropped through it earlier. What occurred to counter the force of gravity? a. Nothing. The magnet probably just rubbed against the sides of the pipe and the friction slowed it down. b. The magnet induced a current in the pipe, which then induced a magnetic field that opposed the magnetic field of the magnet itself. c. The magnet induced a magnetic field in the pipe, which then induced a current in the magnet that counteracted its motion. d. The magnetic field of the Earth opposed the motion of the magnet. It had nothing to do with the pipe
