Calibration of axial DC magnetic field up to 1 tesla at SCL

This paper presents the method used at SCL to calibrate magnetic field measurement instrument (i.e. teslameter or gaussmeter) for DC magnetic field in axial direction, 50 mT to 1 T, with expanded measurement uncertainty within 0.1 %. The equipment used is basically an electromagnet, which has modified and suitably characterized for such application.
