In 5-axis balance calibration test except rolling moment of 60cmMSBS, the relation between coil currents and magnetic force was able to be obtained by varying current in each coil and measuring the force with an industry manufactured balance with very small influence of magnetic field. Consequently, there is a relation between an appropriate coil current combination and the force which can be decided uniquely, and it concludes that 60cmMSBS works as a 5-axis balance. The errors of drag, side force, lift, pitching and yawing moments are below 1.6, 1.4, 4.1, 0.8, and 0.9% in the tested range, respectively. These figures are the error evaluation limits by accuracy of the balance, and a possibility of being still higher accuracy remains. All the errors shown are due to a loop-like hysteresis. If the balance calibration range narrows, it is effective in suppressing nonlinearity and a loop-like hysteresis, and making the balance error smaller.
