It\`s a very, very ingenious device that doesn\`t need any energy to maintain. With it, you can levitate any magnet in the air!
This product is an outstanding household decoration, popular science exhibits, rare gift of popular science, but also very valuable for scientific research. At present, I can think of suspension bearings, suspension induction motors, earthquake prediction, precision magnetic testing. It is predicted that it will grow with the graphene industry which will be widely used in the future.
Principle explanation
Now I\`m going to talk about his principles and see if I can understand them.
First of all, we all have the experience that when a magnet is close to another magnet, at a certain limit distance, it suddenly sucks together, because the magnetic force between them has exceeded the gravity of the magnet being sucked, and then the magnet is sucked, and the closer the magnet is, the greater the magnetic force is. Finally, it snaps together.
So what happens when we put a magnet on the ground under a pyrolytic graphite, the most diamagnetic substance at room temperature?
Let\`s first understand what diamagnetism is:
Diamagnetism is a category.material(Bismuth, graphite, water, copper, etc.) should be addedmagnetic fieldIn this case, the magnetic field will be weak.RepulsionA kind ofmagneticPhenomenon.
Reference table for magnetization coefficient:
From the above, we can see that the diamagnetic material is the magnet close to it, it will produce repulsion to resist the magnetic field; this is a very small repulsion, so now we put a magnet on the pyrolytic graphite, the magnet will receive a very small repulsion, so we now use this device to install a magnet through the knob screw rod to connect slowly and slowly. When the distance between the magnets near the pyrolytic graphite is greater than the gravity of the magnet below, does the magnet below want to fly into the embrace of the magnet above?
Don\`t forget that pyrolytic graphite underneath also provides repulsion. F repulsion + F priming = gravity G of the magnet is the critical point.
So beyond this critical point, the magnet below is ready to take off now, but as soon as it leaves the surface of pyrolytic graphite, the repulsion of pyrolytic graphite to him decreases rapidly, and now it can be suspended! Let\`s assume that the F repulsion decreases and the F induced increases when the critical point is lost, but the sum of them is equal to the gravitational G of the magnet.
That\`s amazing. I don\`t know what I said. Do you understand?
