The invention discloses an electromagnetic energy harvester based on magnetic force stretching jump. The electromagnetic energy harvester at least comprises a base, a sleeve, a magnet spring mechanism, a rotor, a ratchet wheel pawl, a gear and a rack. A magnet spring mechanism is arranged on the other side of the upper surface of the base; the magnet spring mechanism stores energy under the action of mechanical vibration and instantly releases the energy; the rack reciprocates under the action of the magnet spring mechanism to drive the pawl bracket gear to rotate; and a rotor is arranged in the sleeve, rotates under the driving of the ratchet wheel bracket gear, and interacts with the coil to generate induced current. The electromagnetic energy harvester not only can effectively capture and convert weak reciprocating vibration energy, but also can convert the weak reciprocating vibration energy into high-speed unidirectional rotation motion, so that the energy collection efficiency of the energy harvester is
