Abstract: The present disclosure relates to a passive haptic device comprising a mechanical member moving with respect to a second mechanical member, one of the mechanical members having a plurality of magnetized zones spaced periodically according to a pitch P1, the other of the mechanical members having a second plurality of magnetized zones spaced periodically according to a pitch P2, a force that varies periodically as a function of the relative position of the mechanical members being created by the magnetic interaction between the mechanical members, the magnetic interaction varying according to a period Pt, wherein all the magnetized zones of at least one of the mechanical members are magnetized in the same sense.
