We have independently developed an array type rare earth permanent magnet+electromagnetic fine adjustment system, which forms a stable suspension gap of 20mm between the building block base and the display platform, and can rotate 360 ° with a gentle flick. Compatible with mainstream 8mm square column splicing systems (Compatible), comes with 30 "Maglev Special Lightweight Bricks" weighing less than 2.5 g each, which can be assembled into 50+official designs such as windmills, spaceships, castles, etc. Educational scenario: Predicting the installation of towers of different heights on the base and observing changes in buoyancy; Load cell reading → Record the relationship curve between mass and suspension height. Why does a shift in center of gravity lead to a "rollover"? Family Table Setting: Floating Planet, Floating Photo Frame, Creating Cyber Style Ornaments.
