The invention relates to a magnetic drive operation method of an electromagnetic coil, a magnetic drive mechanism and an impact device. The drive mechanism comprises a coil and a combination body which moves relative to the coil and is formed by a combination of a magnetic induction section and a non-magnetic induction section, the impact device comprises a frame, The hammer body, coil and the controller that controls the power of the coil, Through the unique control of the coil, A magnetic inductor is driven by a magnetic field generate by that coil when the magnetic inductor is energized when the magnetic inductor is locate in the magnetic induction region at the front end of the coil, the coil is de-energized when the magnetron moves to the position of the reverse magnetic field regionof the coil, so as to realize unipolar and unidirectional driving of the coil to the magnetic inductor, ingeniously conceived, A linear or linear reciprocate motion of a magnetic inductor driven by anelectromagnetic force can produce an impact hammer, Impact rammer, pile driver, crusher, foundation tamper, vibrator, etc., or applied in rail transportation, transportation and military field, can use electromagnetic to do work for long-distance and reciprocating operation, with the advantages of direct energy conversion, pollution-free, small wear and tear, etc.
