Hi, I need to build a maglev (magnetic levitation) train for school... I have to show many different ideas and then choose the best, while my information can come from anywhere (hopefully here)...
The ideas I have come up with are as follows:
1. Permanent magnets for train and track
2. Permanent magnets for train and electromagnets on track for varied strength.
3. Electromagnets on train and track (for varied strength)
4. For the last option (the most complicated), I thought of using a permanent magnet track and contolled electromagnet train, which "changes polarity" by using a 555 timer or something (if possible, although this will require a very low frequency...) Reason being, because with all the trains except this one, you have to start them by pushing them, and can only stop the electromagnet trains (in a disasterous way)
If anyone knows where I can get info on electro-magnets(and their spelling), maglev trains(and their spelling) has any ideas about the timer circuit for option 4 or has any ideas, comments or wisdom to share please do, because all of it is needed and will be greatly appreciated (including help with spelling)... Thanks...
