Main advantage with maglev train is its levitation due to which it stays away from its track with the help of magnets and reduce friction significantly when it moves forward. In this post we will discuss about this train in detail.
What is magnetic levitation?
It is a method by which an object is suspended with no support other than magnetic fields.We have already seen in maglev train project that how we can use it for our benefit.This technology is very important because it eliminates losses occurred by friction.Other than trains, it can be used for magnetic bearings and high-precision platforms.It has three important parts first is levitation or suspension, second is propulsion, and third one is guidance.
How to build one?
Build your own simple magnetic train !
Halbach Array: It is a special arrangement of permanent magnets that cancels the magnetic fields of one side of a magnet using special arrangements.The train consists of at least two sets of Halbach arrays. One set is placed over the track to levitate the train, while the other set is placed above the motor to provide
If a small magnet is brought near a superconductor, it will be repelled because induced super currents will produce mirror images of each pole. If a small permanent magnet is placed above a superconductor, it can be levitated by this repulsive force.
Though magnetic levitation is difficult to implement , it works on the simple concept of magnetic property that is opposite attracts and like repel. So, this train and it rails were designed in such a way that each and every time half magnets push it forward and half pull towards it.
For Propulsion you can use Linear Sequence motors which instead of producing a torque (rotation), produces a linear force along its length.

Experiments with magnets interacting with other magnets : This is a great demonstration of like poles repelling each other. We have a platform which floats above a pair of magnetic tracks, and can be gently pushed to one end or the other.
