Here is a possible concise summary:
The video is about the history and science of magnets and superconductors, and how they are used to create magnetic levitation trains. The narrator explains the different types of magnets, such as natural, artificial, permanent, and electromagnets, and how they interact with different materials, such as iron, copper, pyrolytic graphite, and superconducting ceramics. He also shows some experiments with magnets and superconductors, and demonstrates how they can levitate objects or create powerful magnetic fields. He then travels to Japan, where he visits a research center and a test track for magnetic levitation trains, which use superconductors to achieve high speeds and low friction. He also promotes his new project in chemical research and applied chemistry, and his account on Wust, where he posts additional materials and videos. He concludes by inviting the viewers to like and subscribe to his channel.
Here are some possible facts extracted from the text:
1. Scientists in South Korea have managed to sustain a nuclear fusion reaction running at temperatures in excess of 100 million°C for 30 seconds for the first time.
2. The core of the Sun has a temperature of 15 million degrees kelvins.
3. A computer testing engineer is a person who is responsible for the final quality of an IT product; his task is to find errors, analyze them and send a report to the developers.
4. Magnets appeared in everyday human use only a hundred years ago, and before that people could not think that there would be such materials that could simply stick to each other without any glue or any other auxiliary means.
5. The first metals from which a magnet was made were iron and copper winding, and this is not without reason since iron turns out to be the most magnetic of all metals.
6. In the city of Nagoya, located in Central Japan in 2005 for the world exhibition, they built an entire metro line based on an electromagnetic suspension in which iron is involved; the trains here move on a magnetic levitation without any wheels.
7. Neodymium magnets are several times stronger than all known ones, and yes, those pieces that you see on the screen are fragments of a neodymium magnet after an impact.
8. High-temperature superconducting ceramics lose absolutely all electrical resistance when cooled to the temperature of liquid nitrogen, then they will also lose absolutely all electrical resistance and when a magnet approaches it, the currents created will be simply infinite.
9. Low-temperature superconductors lose absolutely all electrical resistance only at the temperature of a liquid gel, which has a boiling point of -269 degrees Celsius; it is extremely difficult to get it today.
10. In the city of Yamanashi near Tokyo, Japan, scientists have been testing a future magnetic levitation train since the 60s of the 20th century, which will connect the city of Tokyo and Nagoya, the fastest land transport line on which the train will travel with speed of 500 km/h.
