A cyclotron magnet is studied at Institute of Modern Physics, Chinese Academy of Sciences (IMP, CAS), and the whole system include one main magnet and other magnetic gradient correctors, which is used to accelerate the Kr²⁶⁺ beam. The structure of superconducting coils and room-temperature iron core are adopted for the main magnet. This paper describes the magnetic field design of the cyclotron, and several shimming methods are used to meet the isochronous magnetic field of Kr²⁶⁺ beam,
