The common strategy for reducing static and lowfrequency magnetic fields in a specific region consists of surrounding the volume of interest with a layer of material with high magnetic permeability. However, if for some reasons, ferromagnetic materials are undesirable, rotating conducting nonmagnetic screens could be applied. In this paper, we discuss such a possibility in a quantitative way. Analytical solutions are obtained for infinitely long cylindrical shells rotating in a uniform, static, and time-harmo…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
