T’s amazing, without wheels, Magnetic Levitation Express uses magnetic levitation technology. Electromagnet, propulsion magnets and levitation magnets are used to create propulsion. These scientifically placed magnetic strips are built in the side of guide-way (included) to allow the Magnetic Levitation Express to hover stably and run smoothly at high speeds. After building the 27.60CM x 3.65CM x 2.97CM train kit and 73.66CM x 45CM x 3.40CM rail kit, the user can learn the basic principles of how magnets repel and attract each other. It is ideal for a do-it-yourself science fair, after-school, or summer workshop project with the bonus gift of learning electro-magnetic theory. Experts believe that the retention of child’s learning experience is multiplied if they can coordinate reading with actual hands on experience. With only 155 assembly parts, it’s a wonderful instrument for the beginner enthusiast 8 years and up, and a gateway to ignite opportunities in fun-learning.
