Driving without wheels,flying without wingsWhat is Maglev?

Maglev is a propulsion that uses magnetic levitation to propel vehicles with magnets without wheels, axles and bearings.

Magnetic levitation by attraction:

In order for the train float,there must be two coils.The top coil is installed in the train and the bottom coil is placed in the track .Attraction is caused by having the currents within each of the circuits , traveling in the same direction

Magnetic levitation by repulsion:

Similar poles of a magnet repel each other . In order for the train to float , there must be two coils.

The top coil is placed within the train and the bottom coil is placed on the track . The current in the top circuit travels in the opposite direction of the current in the bottom , resulting in the repulsion between two coils.

Principle of maglev:

In this,there are forces which push the superconducting magnet upwards and ones which pull them upwards simultaneously, thereby levitating the Maglev vehicle.

Principle of Lateral guidance in magnetic levitation

An electric current resulting in a repulsive force acting on the levitation coils of the side near the car and attractive force acting on the levitation coils of the side farther apart from the car.

Principl e of propulsion:

A repulsive force and an attractive force induced between the magnets are used to propel the vehicle

Speed in magnetic levitation

The train can travel at about 300 mph. (acc. can go only up to 200 mph).

For trips of distances up to 500 miles its total travel time is equal to a plane.

It can accelerate to 200 mph in 3 miles, so it is ideal for short jumps.

Noise polluction:

The train makes little noise because it does not touch the track and it has no motor. Therefore, all noise comes from moving air. This sound is equivalent to the noise produced by city traffic.

Magnetic field:

The magnetic field created is low, therefore there are no adverse effects

future of maglev:

Magnetic levitation is a phenomenon that is likely to have considerable potential in the future. Particularly through the use of superconductive levitation.
A new idea for magnetic levitation is in the use of storage of energy. Very basically it uses a rotating ring (flywheel) that stores (kinetic) moving energy which can be 'extracted'
