Exclamation how to make a maglev train move

hi, I've working on a model of a maglev train, using small magnets aligned in two rows simulating the tracks, and some magnets under the "train", I made the train levitate, which is part of what I want to do with it, but I'm having troubles to make it run, or at least move a little forward and not just levitate in the same place. Do you how to make it move? someone told me it was just by using a complicated circuit that made the magnets change polarity in certain sequence, but that this circuit was only made in a laboratory . So, I was wondering if there is another way to make it, maybe by making a "bit of electricity" to run throughout the magnets, but how?

please send some ideas, I'll try them out. I need to have it done for monday, that means I only have a day and something.

Thanx for taking time

Interesting...I never thought anyone would attempt to make one, cause I saw that problem already. But, would it be okay if you move the magnets with your hands? Or are they actually attached in place?

I'm just wondering if you can utilize an electromagnet. You have regular magnets, so I guess there's no point in using electromagnets. But just wondering...if you have a railway aligned with more than two electromagnets, so that you can turn the electromagnets on at different times. For the first electromagnet, make it repel at the end of the train and attact at the front. Then make the end of the second magnet (next to the front of the first magnet) attract while make the front of the first magnet repel. I'm not sure if you can switch changes on electromagnets, but it's an idea...

As for switching polarity, try doing some other research about it. I'm pretty sure you'll get some other ideas, whether they'll work or not is up to you to find out. good luck!

One way if you have a circular track is to attach a computer fan and a very light battery to it facing backwards kind of like those boats you see in swamps.

Thumbs up Thanx

hey guys, thanx for all the ideas. I could finish my project, IT WORKED!!!!!!!!!!!!!! it was kinda simple at the end, to make it move, I had to push it with my hands, I didnt have enough time to build a mechanism that could give it the starting push. But it did levitate and ran without touching the tracks

so again, THANX FOR YOUR SUPPORT

Talking Hey

yes it was indeed Dreamer, I'm proud of the work we made. Sadly we didnt win, but anyways, it was cool. I have some pics of the train if someone wants to check them. Again, thanx.

Procedure for How to make a maglev at home

1 Take a roll of double-backed sticky tape, a piece of cardboard, 20 to 30 small magnets (square ones work best) and ideally one sheet of Perspex.

2 Cut two strips of the tape no more than 1m long. Take 20 magnets (setting aside five for later use) and stick them to the tape. Try to space them as equally as you can, all facing the same polarity. To check this, run a spare magnet over each row. It should either be attracted or repelled by all the magnets in the strip. Now tape the magnets to the cardboard base of the box in parallel lines close to the sides of edge of the base. This is the guideway.

3 To prevent the maglev from leaving the guideway, build two walls. Cardboard will do, but Perpex is best because the point of this experiment is to see magnetic levitation in action. You should now have a makeshift open-top box with the Perspex constituting the longest sides.

4 Now you need a train. Cut a rectangular piece of cardboard that fits inside the guide walls. Attach four magnets to the corners of the train. Be sure that all four magnets are placed so that they are repelled by the magnets on the track. Place the train gently above the track inside the guide walls and watch it float. Hey presto! Magnetic levitation.

5 A gentle push will move the train along the track, but if you want to be really posh, use another magnet. With the lack of friction and wind resistance the maglev should float to the other end.
