Abstract :
The trajectory of a spherical magnet falling inside a cylindrical, conducting pipe is modeled considering both the rotation of the magnet and its horizontal displacement. The electromagnetic force and torque are obtained via a T-a 3-D FE formulation. The calculated trajectory and rotation are compared successfully with the experimental data for different pipe diameters.
