♻️ Eddy-Current Separator: Sphere Polarizability and Flight Trajectories (2D)

Side view of a belt running over a drum with a fast spinning ring of magnets that throws conducting metal pieces forward while plastic and glass drop straight off the belt. Set the number of poles, the rotor speed, the magnetic field, the belt speed, the particle size, the drum radius and the splitter position, and see the field frequency, the skin depth, the repulsive acceleration and where each material lands. The polarizability limits, the ballistic flight, the force and energy and the two conductivity regimes are checked numerically, with four in-page numerical checks.
