Abstract
This paper investigates the application of sensitivity analysis to the calculation of electromagnetic field quantities, such as force. This is particularly important in the design of electrical devices. The electromagnetic field is described by means of a finite element network model which is similar to the classical finite element method. Tellegen´s theorem is then applied to the network model to assess the sensitivity analysis. The method is simple requiring only one calculation of the electromagnetic field, for any small perturbation of the system. An algorithm and a 2D magnetostatic problem are discussed
