Real maglev train uses superconductors and electromagnets. If you use neodymium magnets better idea is using magnets only in train to reduce weight of a train and surface friction.
Magnetic games , I think this project is the best project that I could present to my teacher .so I have a question ....did you use batteries to make the propeller work...?
i advise that two ways for improving this system. first substitute the permanent magnet with some electromagnet, because if you try this experiment with a longer railway, you don't need to find so many permanent magnets. second is to notice the friction between the plastic board and the railway. when the "metro" goes, it must be vibrating all the time, so this vibration can lead to the friction and the friction will slow it down. try some way to reduce it.
+刘猫 thanks for the advice, the friction problem I know him well, I have worked hard to reduce it but it is very difficult to cancel it. The solution electromagnet instead of the permanent magnets is much better, it is possible that in the future I will make an experiment
Magnetic Games my opinion for reducing friction is: to make four wheels.then fix two wheels on each plastic board.the wheels's diameter could be very small and the surface should be smooth enough and they can be rotated easily.but the diameter of wheel need to make sure that any vibration cannot make the plastic board and the rail touch any more.so because the friction is not produced by the gravity of the cart itself, it will not go a very large value actually.
刘猫 No don't reduce friction for wheels, as more friction = More grip for the wheels and smoothening the surface would be like running with on wet tiles with rubber shoes, however you can make indents where the wheels will go which can help guide the train with much less material
Hi friend, very nice train :-) How much did you spend on the magnets? You should really make a circle track, then it can go for hours, also a more quiet fan would be better ;-)
les aimants on un coup bien trop elever et sont trop rare pour en faire des rails, de plus le ventillateur fonctionne sur battery et n'offre aucun control, pour en faire un train ... ... cependant cela ressemble a une catapulte pour planeur :)
Hey you done a very good job! Actually I am making this project for my school.. I am having some issue related to stability! Do I need to fix the glass tightly to the track? Or There is a distance between plexi glass and track? Please guide
Pensavo invece si trattasse della densità del flusso magnetico che secondo me si presentava sia anteriormente che posteriormente al treno. Grazie per il riscontro fornito.
Hello, with my students we are in the middle of a project. We are also planning to build a wehicle like your train. We can't have a propeller on the train and we can't touch the train as well but we need to be able to move it. What would be the best way to move it? I thought about having more magnets in the back of the train (-) and push it with some magnets(+) in our hands ( without touching it. ) or a small fan in our hands and a small sail on the train. Do you think these would move the train? What was the friction like on your train?

looks like 1 solid piece of unistrut for the track and you are shorting some power supply across the track to transfer power to the cart...the cart is essentially in parallel with the track and gets same DC voltage but very little of the current as the impedance of the strut is almost nothing? Or is there a hard to see electric wire taped to the rail we can't see?
there 'no electric wire that transmits current. the current is transferred through the sheet metal rails. In effect, the electrical resistance is high, in 3 meters of rail lose 2 volts
+paul sawford the magnets in this experiment only serve to levitate the train and reduce friction to a minimum to minimize the power of the engine. for an elevator would not serve
You mean electromagnets? Yes. Also you need electromagnets, because to really make a maglev train, you need to change the magnetic field over time, to keep the train from falling off the tracks, without the guiding rails. There's no arrangement of permanent magnets that can secure another magnet at a certain point in space, aka magnetic levitation. All arrangements of permanent magnets are in some way meta-stable. You can overcome this by using superconductors, but then those are also considered meta-stable, because instead of "regulating" the field, you "regulate" temperature.
+Leonardo Cremonesi ciao leonardo sono italiano. La nas è un piccolo server ... Non è il caso di comprarlo apposta x fare questo esperimento prova ad arrangiarti con pezzi di plastica o legno di recupero avvitati o incollati insieme.
Magnetic Games ah scusa non credevo fossi italiano ahah comunque grazie, proverò a costruire qualcosa io! Se utilizzo un pezzo di metallo il peso non dovrebbe influire giusto?
Il peso non è il problema , ma nel metallo anche se non è ferromagnetico si generano delle correnti patassite che possono influire negativamente sull esperimento. Se puoi meglio la plastica
+Magnetic Games ciao avrei bisogno di farti qualche domanda sul progetto (che sto portando avanti) perché sto riscontrando problemi (in particolar modo la struttura di plastica con sotto il cartoncino coi magneti si attacca al binario sottostante e invece che levitare si attacca). Sarei grato se mi potessi dare qualche consiglio, qui la mia e-mail leocremo9@gmail.com
You have to pay attention to the direction of the magnetic field. The magnets I used in this experiment have the direction of the field perpendicular to the 4x20mm side and not to the 4x4mm side
