A method and a device for cartilage regeneration are provided. The method for cartilage regeneration has steps of: applying a pulse magnetic field with a magnetic pulse device to a body part of a mammal in which an injured cartilage tissue is located, wherein the magnetic pulse device has a magnetic pulse generator and a coil, and by applying a magnetic pulse with a frequency of from 10 Hz to 200 Hz to the coil, a uniform magnetic field distribution is produced in a region of the body part covered by the coil, thereby achieving a uniform magnetically induced electrical excitation. The method can effectively facilitate articular cartilage regeneration, and is convenient to operate, having a broad prospect in clinical applications.
