Evaluation of electromagnets for use in calibration procedures


The calibration of magnetic field transducers uses electromagnets with cores of ferromagnetic material to generate high intensity fields. In this case the calibration procedure is done by direct comparison with a standard meter. The homogeneity and stability of field affect the uncertainty of the process, so the measurement of field gradient is required to estimate these levels of uncertainty.
