- Electromagnetic suspension (EMS) uses the attractive force between magnets present on the train’s sides and underside and on the guideway to levitate the train. A variation on EMS, called Transrapid, employs an electromagnet to lift the train off the guideway.
- A new kind of transport: the electromagnetic 'train'. US company Hyperloop One has agreed a deal with Dubai to build a new near-supersonic train to connect two main cities in the United Arab Emirates (UAE). The train would connected Dubai and Abu Dhabi, and it would travel 150 km in 12 minutes. The aim is to reduce bad traffic conditions.

The Maglev can also run in a different way. In Japan, the scientists used the technology of Electrodynamics Suspensions. To understand the idea of this technology, some understanding of electromagnetic induction is required. Electromagnetic induction was discovered in 1831 by Michael Faraday. The basic idea is that changing a magnetic field will cause an induction in current. As shown in figure 3, when the magnet moves through the coils, which is a conductor, the magnetic field inside the coil gets changed and inducts the current. This idea is used in many different fields and has a wide variety of applications. Electric generators, electric motors, transformers and pickups for electric instruments are a few examples. There are few rules we should know in order to understand electromagnetic induction. Faraday's law of induction states that a potential difference is induced in a loop when the number of magnetic field lines passing through the loop changes with time. Lenz's law states that an induced current will have a direction such that the magnetic field- due to the induced current- opposes the changes in the magnetic flux that induces the current.
