Maglev train

Magnetic levitation train, also known as maglev train, is a high-speed train that uses magnetic force for levitation. Maglev trains do not require contact with the track, so they have higher speed, less noise and less vibration compared to traditional wheel-rail trains. The operating speed can reach over 500 kilometers per hour, making it one of the most advanced means of transportation in the world.
The operating principle of maglev train is based on the interaction of electromagnetic induction, utilizing the force between the permanent magnet and the electromagnet to achieve levitation. The electromagnet generates a magnetic field when applied with electric current, and this magnetic field drives the movement of the train. Therefore, the power source is electricity, and its impact on the environment is minimal during high-speed operation.
Compared to traditional wheel-rail trains, maglev trains have many advantages. Firstly, maglev trains have higher speed, significantly reducing travel time between cities. Secondly, maglev trains have less noise and vibration, improving passenger comfort. In addition, since maglev trains do not use wheels, maintenance and wear-and-tear costs are reduced, and their operations can continue for longer periods of time.
Currently, maglev trains have been widely used and promoted around the world. For example, Japan’s JR-Maglev and China’s Shanghai Maglev Train are both in the category of maglev trains. Although there are still some restrictions and challenges in both the technology and operations of maglev trains, through constant innovation and development, this advanced means of transportation is expected to gain even wider application in the future.

client purchase strong magnets"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

customers buy permanent magnets"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
