This thesis presents a method to separate non-ferromagnetic metals based on eddy current phenomenon. Eddy current separators are among the effective approaches for separating non-ferrous metals from other materials in recycling procuders. According to Lorentz's law, when a metal is placed in a time-varying magnetic field, the eddy current flows into it and changes the trajectory of metallic particles. In general, these separators can be divided into two categories: permanent magnets and linear motors. In a widely used method, recyclables are placed on a conveyor belt. At the end of the conveyor belt, there is a drum whose surface is covered by permanent magnets with opposite poles, which rotate at high speed. Non-ferromagnetic metal parts fall slightly ahead of other non-ferrous materials and are separated. The primary problem-solving method in this study is the finite element simulation by Maxwell software. The structure of the rotating magnetic cylinder is then simulated in this software to verify the accuracy of the mathematical and simulation models, and the results were compared. Then, two static magnetic structures based on the ferrite core and the electric coil were presented. The advantage of these structures is their increased frequency, lower depreciation, and lower cost compared with their permanent magnet counter parts. Different factors are affecting the repulsive force in these structures, such as the ampere turn, frequency, dimensions of the non-ferromagnetic metal body, and its distance from the magnetic core. In this study, we investigate these factors and the advantages and limitations of the suggested sturctures through simulations. Experiments were carried out to find the amount of force applied to the metal parts by a test system. Metal parts, such as a pendulum, were placed in front of magnetic structures, to measure angles of deflection. Then the simulation test results were compared with experment tests results to verify the validity of the design methods.
