Nice CGI although there were some errors. The magnetic field forms in a loop around a current carrying wire. Those lines can either represent field direction or field contours (points of equal strength). Some of the time the contours go in the direction of the magnetic field and sometimes in the direction of the electric field. At some points you see a field forming from a wire inside the wall in a loop structure (direction of the magnetic field). Other times you see the field branching out of a wire in paralell with it and them re-entering it further on (direction of the electric field).
