Once, when it comes to magnetic levitation, people think it is impossible to do. But later with the development of magnet technology, gradually appeared electromagnet and strong neodymium magnet. The maglev train is based on this technology. Its principle is based on the design of the magnetic field of the magnet.
Now there was some one used some neodymium magnets to do small magnetic levitation train toys and maglev gyro, these design are very interesting. The material need ready some neodymium magnets, and diamagnetic materials. Now pyrolytic graphite is one of the most diamagnetic materials known to man. Diamagnetic means that the material repels either pole of a magnet. In the website, we can find many interesting design for levitation experiments. If you are interested, you can try it.
