An air core pulsed magnet named Ceramics chamber with integrated Pulsed Magnet(CCiPM) was developed as a fast dipole kicker at first. Because of its flexibility of magnetic field, an octupole-like magnetic field can also be generated. A prototype of an octupole type CCiPM was fabricated for electron beam injection at KEK Photon Factory (KEK-PF). The magnetic field performance of the octupole type CCiPM is measured for DC and pulsed current supply. Some measurement subjects of eddy-current magnetic field evaluation and background noise treatment around zero approximate magnetic field region at the center of magnet are discussed.
