The Magnetic Levitation may be a way of suspending objects without any support in the air, as in case of gravity defiance. An unrecognized marvel from the past which is presently being utilized in useful and interesting applications.
As a child many must have seen a suspended ping pong ball in air at the mouth of vacuum cleaner’s pipe. The magnetic levitation, also referred to as maglev is utilized in a comparable way to suspend objects in the air without support from anything, utilizing only magnetic field. All the magnets, whether electromagnets or natural, have north & south poles. Its well-known that unlike poles attract and like poles repel. The magnetic levitation is the outcome of the repulse created as a consequence of two similar magnetic fields. A thing is said to be suspended when the created force by electromagnetic repulse matches the weight of that thing. Actually, it's the force of electromagnetic balancing the gravitational force.
Obtaining Of Maglev
It is demonstrated that the magnetic levitation cannot be acquired only by utilizing a static ferromagnetism, as this will only make the object instable. In order to generate legitimate condition for magnetic levitation, superconductors or diamagnetic materials need to be utilized. But in each and every case a small assistance from pseudo-levitation must be taken. Pseudo-levitation is that system that gives stability to the object suspended by employing a magnetic mechanism. In case of light objects, magnets manufactured from diamagnetic materials are adequate.
Maglev Future and Present
The trains running on Maglev is one of the popular applications of the maglev innovation. Nearly all the major economies have such kind of trains as a primary mode of transport as a part of their transportation system. Beside this, maglev toys are moreover very popular and are accessible in every market. A few of the popular toys related to maglev are maglev toy cars, maglev toy train, maglev clocks etc.
Future could see maglev innovation put to utilization in numbers of applications. Maglev cars are the part of future of maglev under development phase. These cars will not require a track but will fly in the air. NASA is also working on a catapult using maglev technology that's anticipated to diminish the costs and propelling issues of a space shuttle. Moreover, Maglev lifts are as of now made and will soon be put to utilization in China and Japan.
Also fans are been developed using the maglev technology giving low noise, superior performance, and long life. By utilizing forces of magnetic levitation, these fans include zero contact with no contact between bearing and the shaft.
