This series of products are only for school teaching. If you buy it personally, please build it on the basis of understanding the principle. If you don't understand it, please don't buy it! Thank you! [Magnetic suspension gourd] like a gourd, one end of the gourd has a pointed contact, touching a small transparent plastic sheet erected on the base, as long as the surrounding environment remains unchanged, according to the principle of energy conservation, it can be Rotate, but it will stop in more than ten seconds to one minute. Only in the ideal state of vacuum can it stop forever without batteries. [Packing quantity] 100 [product weight] 0.171kg [product material] ABS + magnet [product packaging] exquisite packaging [product size] 14*8.5 * 6Cm [magnetic suspension experimental material package] magnetic suspension train using the principle of "same-sex exclusion" of magnetic field, let the train have the ability to resist gravity, make the car body completely out of the track, suspend at a distance of about 1cm from the track, and fly into the air. This experiment also uses this principle to suspend the pen. Does it feel amazing? Let's see if you can suspend the pen.
