win?

>>	Anonymous Sat Jun 26 22:21:53 2010 No.1276902 back to /b/ faggot

>>	Anonymous Sat Jun 26 22:21:53 2010 No.1276904 magnetic roads wouldnt be expensive at all, its a wonderful idea!

>>	noko Sat Jun 26 22:21:53 2010 No.1276909 But how do they work?

>>	Anonymous Sat Jun 26 22:21:53 2010 No.1276900 >>1276893 If it's magnetic, wouldn't it just stick to the road...?

>>	Anonymous Sat Jun 26 22:22:53 2010 No.1276910 >>1276900 no there opposite

>>	Anonymous Sat Jun 26 22:22:53 2010 No.1276914 reversed polarity? so they repsel each other? not op

>>	Anonymous Sat Jun 26 22:23:53 2010 No.1276920 if you are a troll.. come on magnets are getting old. If you arent a troll i feel bad for you

>>	Anonymous Sat Jun 26 22:23:53 2010 No.1276926 >>1276910 Then wouldn't they just repel?

>>	Anonymous Sat Jun 26 22:24:53 2010 No.1276933 THIS IS NOT HOW MAGNETS WORK GUISE

>>	Anonymous Sat Jun 26 22:24:53 2010 No.1276935 File: 105 KB, 1106x734, 1277605231289.jpg [View same] [iqdb] [saucenao] [google] a magnet at that size would do this shit to the car fag

>>	Anonymous Sat Jun 26 22:24:53 2010 No.1276936 >>1276926 yes and create thrust to push it forward

>>	Anonymous Sat Jun 26 22:26:53 2010 No.1276949 Brakes, how do they work?

>>	Anonymous Sat Jun 26 22:28:53 2010 No.1276973 >>1276960 Therefor it would work.

>>	Anonymous Sat Jun 26 22:29:53 2010 No.1276979 Congrats OP, you've just invented the maglev train.

>>	Anonymous Sat Jun 26 22:31:53 2010 No.1276997 >>1276960 All Earnshaw's theorem shows is that stable levitation is impossible (except: see superconductors). This just means it is unstable, not that it isn't levitating.

>>	Anonymous Sat Jun 26 22:34:53 2010 No.1277013 How would you turn in this? Wouldn't the car just rotate? Seems like you need to draw a few airfoils on that bad boy OP. I suggest a horizontal tail wing for longitudinal stabilzation, with a couple side wings for horizontal stabilization.

>>	Anonymous Sat Jun 26 23:19:53 2010 No.1277327 fail!! the amount of magnetic force required to lift something like a car would require an extremely powerful electromagnet therefore needing a massive amount of electricity running through the road at all times.

>>	Anonymous Sat Jun 26 23:41:53 2010 No.1277499 >>1277327 Question on magnetic shit: Aside from the resistance from the coil, would the massive electromagnet "use" any power? Just trying to get my head around magnetic force.

>>	Anonymous Sat Jun 26 23:42:53 2010 No.1277515 >>1277499 Yes. Since the vehicle would be moving, there would be a magnetic field moving over a conductor = current = something besides resistance to deal with.

>>	Anonymous Sat Jun 26 23:42:53 2010 No.1277516 You realize that angling the magnets would require some sort of energy source, since they normally want to remain parallel.

>>	Anonymous Sat Jun 26 23:45:53 2010 No.1277540 >>1277515 So, ... How does the law of thermodynamics relate to natural magnets? Do they "run out" of their magnetic properties?
