Questions regarding the Maglev Train project.

[mtugs0702]

I have some questions about this project:

Will the magnetic tape be strong enough to hold the train's weight?
Can I replace the magnetic tape with neodymium magnets?
Can the train work if neodymium magnet is 10mm wide?

Thank you for your time.

Hello!

Here are the answer to each of your question:
1.Will the magnetic tape be strong enough to hold the train's weight?
Usually yes. Magnetic tape should be strong enough to carry a light train (example: wooden block, plastic train...), but it can fail if you have a train that is too heavy (example: fully metal train). Overall though the train should float with most common trains.

2. Can I replace the magnetic tape with neodymium magnets?
Yes. This is very doable, but it makes this build way harder to build. You would have to make sure that they are properly aligned with each other so that the train doesn't crash. Also you will have to make sure the magnets will be close enough to each other or else it will be a bumpy ride. Overall though it should work.

3. Can the train work if neodymium magnet is 10mm wide?
Yes. Since they are smaller it will make the build harder, but as long as you make sure that all of the rails are aligned and close to each other. Again, this will make a slightly bumpy/steppy train ride, but overall it is doable.

Overall I personally would suggest the magnetic rails as it makes the build significantly easier, but it is possible to build it with neodymium magnets.
