Exploring the Magnetic Levitation Technology: The Maglev Train at Iechi World Exposition

The video tutorial explains the concept of superconducting electromagnets and their application in magnetic levitation rail systems, particularly in Japan. It highlights a public demonstration where a superconducting electromagnet floats above another magnetic field, illustrating the principle behind maglev trains. The tutorial discusses the development of maglev technology in Japan, including a prototype that set a speed record of 581 km/h in 2003. The maglev's ability to eliminate wheel-to-rail friction allows it to achieve higher speeds than conventional trains. The video also mentions the maglev's role as a key attraction at the World Expo, expected to draw millions of visitors.

What are the expected visitor numbers for the maglev attraction at the World Expo?

What limitation do conventional trains face regarding speed, and how does maglev technology address this?
