The invention relates to an electromagnetic energy converter which comprises at least one magnetic circuit capable of inducing a variation in the magnetic flux through a conductive coil (200). In this respect, the magnetic circuit comprises a yoke (300) laid out to pivot around an axis of rotation between a first P1 and a second P2 equilibrium position stabilised, respectively, by a first fixed magnet and a second fixed magnet.

Also, the two magnets are laid out such that the stabilisation of the yoke (300) according to one or the other of the first P1 and second P2 equilibrium positions enable the circulation of a magnetic flux in the conductive coil (200), respectively, along a first direction and a second direction opposite to the first direction.
