A three-dimensional finite element method is applied to model a magnetic force control device. This device is based on the use of a magnetostrictive rod in order to control the magnetic force applied to a movable yoke. The paper introduces an original approach to model magnetostrictive phenomena and presents comparisons between numerical and experimental results.
