Definition

Noun: A technology, particularly for high-speed transportation, where an object (such as a train) is suspended, lifted, and propelled by magnetic forces, eliminating physical contact and thus friction with the track.

Usage

This term refers specifically to the technological principle and system that enables frictionless movement. * The new train line utilizes magnetic levitation to achieve unprecedented speeds. * Magnetic levitation is often abbreviated as maglev. * The efficiency of the system depends entirely on the stability of the magnetic levitation.

Advanced Usage

• As a modifier: The term is frequently used attributively (like an adjective) to describe related technologies and systems.
  • maglev train, maglev technology, maglev propulsion system.
• In scientific/engineering contexts: It describes the physical phenomenon itself, beyond just transportation.
  • Magnetic levitation is also used in laboratory settings for contactless handling of materials.

Variants and Related Words

• Maglev (n.): The common abbreviation for "magnetic levitation," especially when referring to the transportation system.
  • The Shanghai maglev is one of the fastest commercial trains in the world.
• Electromagnetic suspension (EMS) (n.): A specific method of achieving magnetic levitation using attractive electromagnetic forces.
• Electrodynamic suspension (EDS) (n.): A specific method of achieving magnetic levitation using repulsive forces from superconducting magnets.

Synonyms

• Magnetic suspension
• Contactless suspension (in a technical context)

Related Phrases/Concepts

• Linear induction motor: The propulsion system commonly paired with magnetic levitation in train systems.
• Frictionless travel/transport: A descriptive phrase for the key benefit provided by magnetic levitation.
• Guideway: The specialized track or pathway for a maglev vehicle.

Noun

1. high-speed rail technology; train is suspended on a magnetic cushion above a magnetized track and so travels free of friction
