Waving magnets!

[synchro1]

I waved a stack of eight ceramic block magnets. I then connected my two large opposed neo disks by axel between two six inch plastic coil spools and an eighteen inch plastic wedding cake server dish in the middle. I have it placed on end with half the magnets suspended below from the top magnets over head. That's room for one hundred and twenty eight waving magnets top and bottem. Half the waving magnets hang down and are supported at the fulcrum edge by the adjacent waving magnets over head. I need two pancake spiral output coils one top and one bottem. Pulsing in rythem rocks them to the wall.

If you wanted to capture the energy of transient vibrations it would be easier and less prone to failure if instead of suspending the magnets using the neo disks you used simple springs.

Then locate the device near a source of constant vibrations (busy road?) you could then convert the vibrations into electrical pulses. of course the amount of energy extracted would be determined by traffic patterns.

It would actually make an interesting wind power alternative. not sure you could get much efficiency out of it though.

The combined strength of the 128 ceramic's is 640 lbs of pulling force. I don't have that many magnets. I noticed them on sale for 2 for .99 right now at Harbor Frieght! The wind rocks them like crazy. Mounted on a rotor they would generate some useful power. Pulsing at one magnet's apex would set the entire group fanning. Higher frequencies may yield vortex channels. 1.59 khz, vibrating frequency of magnets. I'll have to upload a video of this. Really looks awesome! This works great. No need for complex geometry. Everything sits right in position with no problem. The double decker worked too cool for words! 


Springs cost a lot of money and are hard to adjust.

"springs cost lots of money and are hard to adjust"

I agree with the first part but not the second part.

At what cost are the big neo magnets. Perhaps not much now because they are lying around. but if you wanted to turn this into a commercial enterprise springs will be cheaper and much more stable.


In fact the little magnets only show the flux lines. You don't need them at all. If you place the neo's on top of a flexible pole and arranged a pickup coil everytime the pole vibrated you would get energy. no small magnets at all.

There are lots of different ways this could be arranged to get the same outcome of deriving energy from vibration. particularly if it was so arranged to resonate.

The best results so far have come from four stacks of five ceramic block magnets, two dangling so it looks like four diamonds, each pair touching at their points from the side. Relay coil is placed at the top of one. The prime mover block magnet rocks a full swing when pulsed with twelve volts through the relay. Pretty impressive travel from a rocker in equilibrium. It sets an oscillation in motion with the other three. I noticed a wrist twisting torque in the adjacent upper stack while holding it. Seems like a real kick has developed from a very tiny input pulse. There are four very stiff kicks that develop and bounce in series from the initial full swing of the prime mover magnet. Appears like an amplification of force at this point.


I tried and failed to upload a video, the magnets destroyed the tape quality. I have to retry. Really a super cool looking setup, an interesting Kinetic Art form at the very least.
