An accurate representation of the magnetisation curve including the incremental permeability curve, is presented. It is based on selected powers of B (not generally integer) with positive coefficients giving a power series. The fit is shown to be superior to those obtained with polynomial and rational fraction polynomial representations.
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.
