Aluminum is a metallic element with symbol Al and atomic number 13.

A magnet coil is a conducting device that performs electrical work by applying electricity to a wire outside a magnet, converting electricity and magnetic forces into mechanical energy. The components of the electromagnet coil are the absorption coil (enameled wire group) and the magnetic force system (magnet). The magnetic system consists of an iron core, a yoke and an armature. A simple conduction structure is housed in a cylindrical housing to perform various electrical tasks. Screw, direct, E, and U are all common forms, but they all have a similar principle. When the coil is energized, the magnetic force will be generated. The inflow end of the magnetic force is the S pole, and the output end is the N pole. Opposite poles will be created at the ends of the magnet, and an attractive force will be created between the core and the armature.

Enameled copper clad aluminum wire has excellent high temperature resistance, mechanical properties, electrical properties, chemical properties and excellent freezing resistance. It is suitable for refrigerating equipment working at 200℃ for a long time, electrical equipment subject to chemical erosion, dry type transformer, oil-immersed transformer, epoxy casting transformer, iron remoter, electromagnet and other mechanical and electrical equipment.

Pure copper is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields, and is second only to aluminum in the consumption of non-ferrous metal materials in China.
