1. A switchable magnet device, comprising:
at least one magnet stack that can be transferred between an interaction position in which the at least one magnet stack is magnetically functionally connected to a formwork support, and a release position in which the magnetically functional connection between the formwork support and the at least one magnet stack is reduced;
the at least one magnet device furthermore comprising a fluid-driven energy transmission mechanism that is coupled to the at least one magnet stack in order to transmit a force to the at least one magnet stack for at least partially transferring the at least one magnet stack from the interaction position into the release position;
wherein the at least one magnet stack includes at least one accommodating section formed at least in the interaction position of the magnet stack which accommodates at least a portion of the fluid-driven energy transmission mechanism within the at least one accommodating section.
