The rare earths (RE) are characterized with their strong metallic atomic bonds. They are used in magnetic materials used in computer technology and electric powered vehicles. The advancing globalization and the increasing standard of living both lead to massive waste disposal problems, therefore, the methods of recovering used metallic materials are sought. In this paper, the microscopic characteristic of magnetic powder from old electric engines has been presented.
