This is used in the track system of high-speed lev trains.  Aluminum instead of copper, and electromagnets instead of neos.

That's cool.:cool:

interesting, dØ/dt  - possibly this works because the parameters are about right, enough flux, enough weight.

Here's the question, where is the reaction force coming from? OK it's magnetism but where is THAT coming from? :huh:

The falling magnet is generating an electric current in the copper tube, which in turn
generates an electromagnetic field, which to it's nature counteracts the permanent
magnetic field from the magnet, hence the braking action of the falling magnet.
Looks really cool :D

eddy currents...

its why we cant find a good way to generate power with out drag on a system...

you want to see something neat... check this out 45tesla Magnet...

watch the hole thing but look at 6 min in... takes a 2Kg aluminum chunk 2.5min to fall 12 feet... :)

cool..

here is a good way to make power.  Use a steam motor, and connect it to a teals cd tubing. use the steam as the driver.
of course a fennel lens to power the steam by solar means
80psi should work fine?

good work on all the hard work.. cheers.:D:cool:

I  tried dropping two magnets glued together (north to north) things really got slowed down going down copper pipe.  You should check out anti-gravity-in a inter-view with Boyd Bushman that worked for Lockheed Martin-senior reseach scientist.   It would be better for you to hear him tell of his reseach on magnets and gravity.  enjoy   fgunsmoke

Do you have a link for that, thanks.:D

Hi All,

In nijmegen, holland they did research with magnetic fields



here they float a strawberry, they also did pieces of pizza and a frog (did no harm)

they locked in the frequency to water to levitate these items

That's cool EZ,:cool: but don't tell my wife, she'll want me to start tossing salad that way.:cool::D:P

As we only see a few revs here I'm a tad suspicious as to why they're not showing like 10 mins of spinning or so..........?
Also, what happens if the magnet were to be bolted to the board, would the wheel then start spinning if you put the ball next to it?
I guess the only (?) way to find out would be to actually build the thing yourself.
Having been building various perm magnet devices of sort in the past I would choose to make a plastic wheel, just to avoid the risk
of magnetizing the whole wheel, with all the probs that follows with that.

Jeff-Have you checked out Boyd Bushman-retired senior research scientist of Lockheed Martin and what he did as a experiment with two magnets bolted together north to north?.  It is on you-tube.     Have you tried  to glue two cheap magnet together and dropping them in copper tube?  NORTH to North - or south to south? I don`t know if Russ has tried this but on his Leedskalnin TPU I built one like the small one he first did and it worked great. For the top bar -I used a soft iron bar out of a transformer. I then reversed the wiring on LED. The Led didn`t light when i jerk the bar off the bolt but it did light each time I put the bolt on with a tap. It didn`t need charged with a battery unless you wanted to lock the bar on- plus you would need to reverse the LED.  You need to use a quick tap like the quick jerk when taking the bar off. this seem like a spike  and doesn`t dim with use.  I  told someone on here about getting water to burn for me but that is the big thing I need to work on.    Having a hard time moving around in here and finding my way back to the same place.    fgunsmoke

Hi GS, I have not seen the video you mentioned, [got a link] or done these experiments. There is soooo much I would like to do  but with working for myself [no money] and taking care of the forum there hasn't been much time left. Iv'e got my 3d printers both done and working. Now that they are done I might have a little time to get back to building and finish my 6" diameter, 2' long clear tube, 3/4 and 1" X 18" SS tubes, 9 cell WFC. Have all the parts to finish, bought them all last year. Great work you are doing. I appreciate and like the experiments you have done, thank you for the updates, please continue to do so, Jeff.:cool::D:P

Jeff--I`ve never moved a link over from one place to here. Just use google search- -(boyd  bushman antigravity experiments).   I`ll find out how about  a link and I can see that I`ll need it over hear. fgunsmoke

The ol' guy is right, nature is constantly talking to us, we just need to learn how to listen.
