heal.abstract	Next to the experimental approach of phenomena concerning plasma and plasma facing components of a tokamak another approach was adopted in this paper, a numerical modelling one. The study was done using CARIDDI, which is a 3D integral code for the eddy current density J, the problem is solved by computing at every edge of the finite element mesh the projection of a vector, the current vector potential T, whose uniqueness can be demonstrated mathematically by appropriately using the notions of tree and co-tree formed by branches of a graph, according to graph theory. A plasma is considered to be a toroidal conductor with an elliptical or rectangular cross-section. The section is subdivided into elements and the plasma current is carried in each single element by a filament, placed in its center.	en
