A magnetic calculation code has been developed for modelling a multi-beamlet, multi-stage negative ion accelerator. This code has been recently improved with a precise and fast calculation of magnetic force between permanent magnets and current-carrying conductors, and self- and mutual- inductances involving rectangular or circular coils. The paper describes the formulation and the validation of force and inductance calculation through comparison with other codes and analytical solutions.

Abstract
A magnetic calculation code has been developed for modelling a multi-beamlet, multi-stage negative ion accelerator. This code has been recently improved with a precise and fast calculation of magnetic force between permanent magnets and current-carrying conductors, and self- and mutual- inductances involving rectangular or circular coils. The paper describes the formulation and the validation of force and inductance calculation through comparison with other codes and analytical solutions.
