The superconducting magnet for RAON 28 GHz ECR ion source has been designed. The designed magnetic field distributions for the 28 GHz ECR ion source were 3.5 T at the injection side, 2 T at the extraction side and 2 T on the inner surface of the plasma chamber, respectively. The magnets using NbTi wires were composed of the four solenoid magnets for axial magnetic field and one saddle type hexapole magnet for radial field. The experiments were conducted at 4.2 K conditions using liquid helium. In this paper, magnet performance results were analyzed based on the balance of the magnetic force. The results showed that the difference in magnet performance was 10 ~ 20 %, according to magnetic force balance affected by the sequence exiting the magnets. Thus, the sequence has an effect on the magnet performance. This results are expected to help in finding the optimal sequences.
