Maglev train

Maglev Train in China recently broke its own speed record, reaching 623 km/h during tests in a low-vacuum tube.

About the Maglev train:

• The Maglev train operates on maglev (magnetic levitation) technology, invented by Hermann Kemper in 1934, which enables it to float above the tracks through magnetic forces.
• Superconducting magnets in the train repel each other like ordinary magnets when similar poles face each other, suspending the train above the guideway.
• To move, power is supplied to the guideway’s coils, generating magnetic fields that pull and push the train.
• The electric current in the guideway walls is constantly adjusted, changing the polarity of the coils to propel the train forward by attracting it towards the front and pushing from behind.
