Abstract :
We adapt the classical variational formulations in field h and in field e and also a mixed formulation in h and e in order to compute the eddy currents in a magnetic and/or laminated medium. The results obtained with the three formulations for the Joule losses are compared. We show the interest of the mixed formulation for inhomogeneous conductors.
