1. An impact striking mechanism, for a horological movement, comprising:
at least one resonant element enabling a sound to be emitted when struck;
a hammer movable between a rest position and a strike position at which the hammer strikes the resonant element in order to cause the resonant element to vibrate;
a system for actuating the hammer including a movable impactor configured to move from a release position to an impact position, in which the impactor at least partially transmits momentum thereof to the hammer to move the hammer from the rest position to the strike position in order to cause the resonant element to vibrate; and
a magnet which is fixed relative to the horological movement, the magnet being configured to attract the movable impactor into the impact position.
