The electromagnetic unit comprises a center bush (35) and a conducting wire (34) wound on the center bush (35). A U shape of one end of the center bush (35), which is bent to the inner side, is formed to be parallel to be adjacent to each other. A piston reciprocates along an inner wall of the cylinder by the magnetic force between the magnet and the electromagnetic unit so that compressed air is generated. An air pressure from a low pressure to a high pressure is generated by efficient use of an attractive force and a repulsive force formed between the piston and a center rod, and the air of the high pressure can be produced in multiple stages. An electromagnet is arranged in parallel, and the parallel inverter circuit unit is used. Therefore, the efficiency of the electromagnet is improved. Therefore, the electromagnetic air compressor can improve energy conversion efficiency in comparison with an existing invention by minimizing and optimizing an air system.
