Electrodynamic forces between flat circular coaxial coils

Object and purpose of research. Non-contact power transfer to various marine facilities. Subject matter and methods. The study relied on the methods of theoretical electric engineering. Main results. This paper gives analytical estimates for electrodynamic forces acting on inductively-coupled coaxial flat coils of circular shape. Conclusion. The study yielded the expressions for the electrodynamic forces in inductively coupled circular coils interfaced so as to perform non-contact power transfer.
