TITLE: The most simple force formula for coaxial cylindrical magnets and thin coils
KEYWORDS: Coaxial cylindrical magnets, magnetic force, thin wall solenoids.
ABSTRACT: In this paper we give the general formula most simplified for calculating the magnetic force for coaxial cylindrical magnets and thin coils. All possible singular cases are automatically handled by the proposed formula. The results of the presented work have been verified by the filament method and previously published data. The new formula provide a substantially simple alternative over previously published approaches, which involve either numerical techniques (FEM, BEM, MOM) or other semi-analytic or analytic approaches.
