A modular assembly set system for use in modular constructions suitable for behavioral research made of a polycarbonate, acrylic or other material walls with magnetic edges, joints and parts with a support base (floor) made of magnetically active metal sheet glued over a plastic inert polymer surface (or one of similar inert properties). The system comprises a multi-piece set that allows the building of different mazes or structures for use in behavioral, memory and health sciences studies. The magnetic edges of the walls along with joints and other pieces attaches to the metal base (floor) and permits to modularly build any configuration. The use of this device can be extended to virtually any kind of modular construction (toys, provisional constructions, stands and other low weight assemblies). The walls and floor set can be used many times, and assemble and disassemble as required.
