The invention relates to a magnetic device which is used to produce a graphic display that is intended for at least two users, consisting of: a writing means which is used to write on a display screen (2 or 2'); a display means comprising at least two parallel faces, one of said faces including a display screen (2 or 2'); and a housing comprising a ferromagnetic element which is disposed between the two parallel faces. The invention is characterised in that the second parallel face also comprises a display screen (2 or 2'). Moreover, the two display screens (2 and 2') are essentially positioned back-to-back at a small distance from one another, such that when a first user is writing on one of the display screens (2 or 2'), the second user can erase all or part of the first user's writing. |
