Do Maglevs float?

High-speed maglev (short for magnetic levitation) trains float on air because electrified metal coils in the guideway, or track, repel large magnets attached beneath the train. Since there's no friction, the train can go fast — more than 300 miles per hour!

Maglev trains do not have wheels or rails. As shown in Figure 3, they have guideways, and they float down these guideways without ever touching them.

Maglev is a system in which the vehicle runs levitated from the guide way (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets onboard the vehicle and coils on the ground [10].

MORE DETAILS

A magnet or properly assembled array of magnets can be stably levitated against gravity when gyroscopically stabilized by spinning it in a toroidal field created by a base ring of magnet(s).

MORE DETAILS

The high cost of maglev systems results from the need for a stand-alone guideway construction featuring active magnetic coils embedded directly into the guideway or on the vehicle and, in the case of the Japanese design, the addition of very low temperature liquid cooled superconducting magnets.

MORE DETAILS

Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.

MORE DETAILS

There are only three countries in the world that currently have operational Maglev Trains: China, Japan, and Korea. Maglev trains are much more efficient than traditional trains and hold the speed record for trains (603km/h).

Hermann Kemper (* April 5, 1892 Nortrup, Germany, in the district of Osnabrueck, † July 13, 1977) was a German engineer and is considered by many the inventor of the basic maglev concept. In 1922, Hermann Kemper began his research about magnetic levitation.

So your magnets never will stick together. In this case if the 2 magnets are touching each other forcely with same pole then they will be act as a one another magnet whose 2 side are north and south but the touching point is mid point. But when they are not in touch they will repulse each other.

Cost: Maglev train technology is significantly more expensive than conventional high-speed rail. HS2 is already a highly expensive project, and adopting Maglev technology would further increase the cost.

MORE DETAILS

Even if the power goes out, levitation forces keeps the train in the air while it is traveling at high speed. The vehicle comes safely to a stop rather than suddenly falling onto the track.

MORE DETAILS

Maglev trains do not create direct pollution emissions and are always quieter in comparison to traditional systems when operating at the same speeds.
