* Descriptif :
* 
*  Le potentiel magnétique vecteur est calculé à partir de J(x,y)
*  et la matrice obtenue par MPMAGV. Le potentiel est en 3D.
* 
*  
*  
* Arguments :
* 
*       (E)     ILREE = Pointeur sur la liste de réels (résultat)
*       (E)     ICHAMJ = J(x,y) en tant que MCHAML
*       (S)     ICHAMA = A(x,y) au milieu de l'épaisseur, MCHAML
*       (E)     IMOD5 = pointeur sur le modèle
*       (E)     MINTE1 = pointeur sur MINTE
*       (E)     NBELEM = nb d'éléments
