Magnetic levitation uses magnetic fields to suspend objects without physical contact. Diamagnetic levitation directly repels diamagnetic materials from magnetic fields, allowing water droplets and other objects to levitate. The Super Levitron demonstrates magnetic levitation through the balanced forces of gravity, magnetism, and gyroscopic forces stabilizing a spinning object. Maglev trains and other applications use these principles to reduce friction through magnetic repulsion or attraction between magnets and conductors. Magnetic levitation could enable more efficient transportation and energy systems with benefits like higher speeds, less pollution, and reduced wear.

2. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended above another objectwith no support other than magnetic field .The electromagnetic force is used to counteract the effects of the gravitational force.Direct Diamagnetic Levitation – How it WorksDiamagnetic materials repel a magnetic field All materials have diamagnetic properties, but the effect is very weak, and usually overcome by the object‘s paramagnetic or ferromagnetic properties, which act in the opposite mannerBy surrounding a diamagnetic material with a magnetic field, it can be held in a stationary position (the magnetic force is strong enough to counteract gravity)

4. Direct Diamagnetic Levitation – ApplicationsWater is primarily diamagnetic, so water droplets and objects that contain large amounts of water can be levitated

13. The rotation of a spinning object’s axis of spin creates a torroid of genuine stability.

14. The top remain levitating in a central point in space above the base where the forces acting on the top- gravitational, magnetic, and gyroscopic- are in equilibrium

15. Stops due to air resistanceWhy it works??? The principleTwo similar poles repel, and two different poles attract, with forces that are stronger when the poles are closer. There are four magnetic forces on the top. The north-north repulsion dominates, and the top is magnetically repelled. It hangs at the point of equilibrium where the total force is zero.”

16. The FutureMagnetic Levitation

17. ApplicationsMaglev Trains- The magnetized coil running along the track, repels the large magnets on the train's undercarriage, allowing the train to levitateBiomagnetism- in MRI Particle accelerators to accelerate sub-atomic particles to nearly the speed of lightIn petaflop computers. A petaflop is a thousand-trillion floating point operations per second.

18. NASAMaglev technology could give space vehicles a “running start” to break from Earth’s gravity

19. Maglev Space Propulsion Launching systems would use magnetic fields to levitate and accelerate a vehicle along a track .Reaching the end of the track, the vehicle could switch to more conventional rocket engines.

20. The History Magnetic Levitation Vehicles

21. 1750 – John Mitchell conducted the first experiments measuring the magnetic forces between the poles of a magnet .

22. 1900 – Robert Goddard and Emile Bachelet conceive the concept of frictionless trains.

23. 1969 – American scientist James R. Powell and Gordan T. Danby patented the first design for Maglev trains.1990 – The initial phase of the Yamanashi Maglev Test Line commences.

24. Magnetic Levitation Wind TurbineMaximum overall efficiency of windmill is 30%.The remaining energy is mainly lost in friction. If the same windmill is operating at 50% of its maximum speed the efficiency becomes very low.

25. Due to wear and tear performance of the machine deteriorates.

26. Normal windmill can start its generation from wind speed of 3 m/s. But windmill using magnetic levitation can start generation from wind speed of 1.5m/s.

27. ADVANTAGES OF MAGLEVtransportationNo surface contact or friction to slow them down. More speed = More passengers. Faster trips

28. High reliability

29. Petroleum independence with respect to air and auto as a result of being electricallypowered..

30. Less polluting

31. Potential for high capacities at 3-4 minutes headways. High safety.

32. Convenient– due to high frequency of service, vibration free train rides and quieter. At speeds below 249.4 kmph the noise produced by Maglev trains is less than that by conventional trains. At speeds above 155 mph, most of the noise produced by vehicle is of aerodynamic origin, whether it is on rail or levitated.
