▲ even if he flipped the copper pipe over,The magnet inside did not fall on the table, but kept floating and moving inside.。It's really amazing,In fact, the copper tube is equivalent to a dense closed coil,There is reluctance when the magnet passes through。i.e. the coil generates current when the magnet passes through it,The current in turn generates a reverse magnetic field in the coil,Therefore, when the magnet passes through, it will always be suspended in the copper tube.。It's amazing to see this,Hurry up and share the article to let more people know about it。。
