So with something as precise as the Levitron is, relying on both magnet strengths, weights, and distances all being in perfect balance, would I be able to actually get good enough measurments to duplicate it on a larger scale without having extremely precise instruments? I'm on a tight...

Is that the same method magnet manufacturers use to test the strength of their magnets? It also depends on the shape of the magnet doesn't it? Depending how the field is shaped rather.

I was puzzling the Levitron today, and was trying to figure out what the magnets involved strength was, on the off chance that I may build a larger one for kicks. However, after some moderate googling, it doesn't seem like figuring out the strength of a magnet is a quick or 'easy' task...

I don't think a chamber that large would benefit me much.

Short cycles are the initial plan, however, one of my modifications is moving the wires outside of the vacuum, the stator assembly (which I'm going to have to build) that I designed is going to be on the outside of the chamber. Which is why the chamber needs to be a non-metal. I don't want any...

Well, that's part of why I have made extreme efforts to reduce friction, to reduce heat and wear on the mechanical parts. So under a machine pump vacuum I should be able to eliminate most of the resistance you think? I would have thought 1.5" lexan would hold a moderate vacuum, that stuff is...

It's hard to explain, the experiment is almost like running an alternator inside of a vacuum, but there's a lot of modification to it. I'm trying to cut down on mechanical resistance (I have made many adjustments to minimize friction) as well as any air resistance.

Well, I don't expect the prototype to be completely flawless. If it works properly, then I might get some outside financing to fund a bigger, more efficient version. I just need to minimize overall air resistance. I will see if I can find some information on what you said. I am sure I do not...

I'm trying to achieve the best vacuum possible for as little money. I'm using my own pocket money to do this experiment, and need as little air resistance within the container as possible. The temerature range would be around room temperature, the volume should be around as much as a 5 gallon...

Hrmmm.. this could be a bigger problem than I'd hoped. The idea of an ideal container would be something in the shape of this: (Sorry, its a paint drawing since I'm at work. Dimensions are subject to change, but not greatly.) http://img12.imageshack.us/img12/714/bbbbhjk.jpg And yes...

I would like to know how you chose to assemble the lexan, if you don't mind. So that I do not make the same mistakes. The only port that will be accessable to the container will be that of the pump.

The build of the container will not be a length of cylindrical container all with the same diameter. It's going to contain multiple 'staged' sizes. That is discouraging hearing about the lexan. Though my lexan design is only going to be a prototype tester model. If it worked, then...

Sadly the jars won't work, it's going to have to be a custom fabricated container... which should be fun to make. Thanks for the link to the pumps though. I have not come across that page yet.

First off, I'm new here. Greetings! I should start off by saying I'm not a genius, as I'm sure some people here may be. I don't have a degree in any of the fields on this website, but all interest me. I like to think I have a general understanding of how some things work, but I know I always...
