In which direction should the current be traveling in the closed loop to generate the magnetic field at the center of the circle with the given direction?. counter clockwise. Copper Pipe and Neodymium Video Clip. [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. .
