The superconducting magnets of the Facility of Rare Isotope Beams (FRIB) are used to focus and steer the heavy ion beams of the driver linac. All the magnets are designed as a solenoid with bucking coils to suppress the stray field, and all the magnets have superconducting dipole correctors to steer both horizontal and vertical field. Two types of magnets have been manufactured in China, and some of them have been tested at Institute of Modern Physic (IMP). This paper describes the test system and magnetic axis measurement method. We also present a summary of the measurement process and test results of the magnetic performance for the magnets.
