(After a week of adjusting and testing) A NIB magnet with some metal pipe is supported motionless, 1 inch below the coil. "..look Ma, no hands.." The circuit uses two linear Hall effect devices at either end of an electromagnet. The circuit senses a difference in the two outputs which should cancel regardless if the coil is switched on or off. An approaching magnet disturbs this balance and this this output is fed to a PWM (pulse width modulated) supply for the MOSFET output to the coil. Conditions are set so that there is an equilibrium is setup with the weight of the magnet and the electromagnet at a certain point where it will hover. Hmmm.. magnetism opposing gravity - sounds like 'antigravity' to me... (click to enlarge) The left photo shows the coil and earlier circuit board. The other two are of the neat side and the not-so-neat side. Alright, so I don't know how to do PCB's.

Levitron Stability Earnshaw's theorem proved conclusively that it is not possible to stably levitate using static, macroscopic, "classical" electromagnetic fields. The forces acting on an object in any combination of gravitational, electrostatic, and magnetostatic fields will make the object's position unstable. However, several possibilities exist to make levitation viable, by violating the assumptions of the theorem — for example, the use of electronic stabilization or diamagnetic materials. Methods There are several methods to obtain magnetic levitation. The primary ones used in maglev trains are servo-stabilized electromagnetic suspension (EMS), electrodynamic suspension (EDS), and Inductrack. Mechanical stabilization If two magnets are mechanically constrained along a single vertical axis (a piece of string, for example), and arranged to repel each other strongly, this will act to levitate one of the magnets above the other. This is not considered

11. Not A Bird Or Plane, Just Shanghai's New Maglev, The World's Fastest Train My flight that's what it was called - was aboard Shanghai's spanking-new Maglev (magnetic levitation) train, the world's fastest, most futuristic passenger line. http://www.gluckman.com/Maglev.html

Is it a Bird? A Plane? Nope, only Shanghai's flashy new Maglev, the world's fastest train. Way ahead of its time seven decades ago, the still-futuristic magnetic levitation system may yet redefine travel everywhere. By Ron Gluckman/Shanghai,China L IKE MANY ON THE MAINLAND, I was on the move over the Chinese New Year. My flight lifted off early on the last morning of the Year of the Horse, touching down at the airport eight minutes later. Yet it never left the ground. My flight - that's what it was called - was aboard Shanghai's spanking-new Maglev (magnetic levitation) train, the world's fastest, most futuristic passenger line. Longest-awaited, too, since it's been an astonishing seven decades since the invention of the process that was finally put to a test on the next-to-the-last day of last year, when Premier Zhu Rongji took an inaugural ride with Chancellor Gerhard Schroeder of Germany, which helped fund and build this line. Now, common cadres were having a turn. Local media called them "joyrides," these series of trial runs to the international airport in Pudong , across the river from Shanghai proper, that add a bit of flash to the Spring Festival. They certainly live up to the billing.

The train is suspended on a magnetic cushion about half an inch above an elevated magnetic track, whose moving magnetic field alternately attracts and repels magnets mounted on the train, which is pushed and pulled along by this process. Wiktionary (1 definition) –noun a method of supporting and transporting objects and vehicles by using a magnetic field to counterbalance the gravitational pull GNU Webster's 1913 (1 definition) –noun The process of supporting an object, such as a vehicle, with a magnetic field so that it does not contact the object supporting it; it is a method used for eliminating friction in moving vehicles, and is used, e.g. in high-speed rail technology where a train is suspended on a magnetic cushion above a magnetized track and so travels free of friction.

Magnetic Levitation: Interdisciplinary Magnetoscience We use strong magnetic fields, up to 17 Tesla, generated by superconducting magnets to levitate water and biological organisms such as plants and bacteria. Within a magnetically levitated object, the force of gravity is balanced by a magnetic force at the molecular level. This means we can investigate the effects of weightless conditions, without needing a spaceship. We can also use the magnetic field to effectively increase the force of gravity, or to apply "differential" gravity to mixtures, such as granular materials, to achieve separation.

How can you use them for magnetic levitation This is slightly off-topic from coilguns, but magnetic levitation has many common design principles and is a little easier to build! How Levitation Works If you hold two permanent magnets close together, you see that one of them will jump strongly toward (or away) from the other. In 1842, Samuel Earnshaw expressed the perversity of inanimate magnetic objects in his theorem. It explains this frustrating behavior will always prevent you from suspending one permanent magnet above or below another, no matter how one arranges the two magnets. However, an active control circuit can get around this problem by rapidly adjusting the magnet's strength. The general principle is straight forward: An electromagnet pulls a ball upward while a light beam measures the exact position of the ball's top edge. The magnet's lifting force is adjusted according to position.
