[2:17]. So, what’s happening?. As the magnet is falling, the magnetic field generated by the magnet is moving through the copper. . The movement of the magnetic field generates an electric current inside the pipe. . Section 30. Previously supposed zero net current.. Then. For a conductor, there can be non-zero net current. Now we suppose there is such.. Then. “Conduction” current density. Magnetization gives no contribution to net current, even though there is surface current.
