Magnetic and dynamic cross-fields have been widely used in plasma torches for multiple purposes: reduction of electrode erosion, increase of the operating power and possibility of control and stabilization of the plasma arc. This paper presents a new analytical approach to model the behaviour of the arc under cross-fields. It is very useful because it provides basic information on the arc without having to resort to costly simulations. An MHD numerical model is used for validation.
