A calibration of the well-defined Braunbek coil system was carried out using the scalar method. The whole measuring setup was designed to minimize the uncertainty of the scalar calibration procedure. The measurement time as well as the sampling ratio were adjusted to reduce the influence of the ambient magnetic field variation. We calibrated the coil sensitivity with the uncertainty of 30 ppm and orthogonality with the uncertainty <0.01°. The results were compared with a different technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
