Vision Of Benjamin Franklin
We may perhaps learn to deprive large masses of their gravity and give them absolute levity, for the sake of easy transport.
INTRODUCTION
Maglev is a new surface mode of transportation system in which vehicles glide over their guideways ,suspended, propelled & guided by magnetic forces.
They don’t require engines.
PRINCIPLE
Maglev works on electromagnetic forces between superconductors on train and coils on the guideway.
Magnetic fields are actively excluded from super conductors (Meissner effect). 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.
CONCLUSION
MAGLEV ,a combination of superconducting
Magnets and linear motor technology ,allows
Super high speed running while keeping it
Safe,reliable,and environment-friendly.
