Combined function magnets with dipole and quadrupole components were designed and built for the Extremely Brilliant Source. These magnets are low power consumption single sided off-axis quadrupoles. The field of the magnets was optimized for particles with a curved trajectory and within an elliptical good field region. A specific moving stretched wire magnetic measurement method was developed for measuring the magnetic length of the magnets, the radius of curvature of the poles and the field multipoles. The effect of the curvature of the magnets on the field multipoles was investigated.
