Pendulum with Magnets (All opposing)

[mr_bojangles]

hmm

pretty cool

so the top magnets repel, and the bottom magnets attract?

has anyone tried to check the length of each swing to see if it was slowing/ how consistent it was?

maybe the very first one compared to the very last


il give it more thought, try to figure out the weight ratios of the magnets then maybe someone can build it

Mr. Bo. ,   I think all the magnets repel.

Hard to fully explain why this shouldn't work as shown...
here is a simple attempt:

as you declare the screw on top of the pendulum in your picture as a battery-holding unit. i think so, it's only to adjust the pendulum-weight for balance.

sorry about my bad english.

i also think so, all magnets repell. the two top-sets is clearly to see. the bottom ones also repel to give a kick to the pendulum for force it with more strength in the opposite direction.

I am sure that if the video was long enough you would see it slow and stop. Just like any other pendulum. This is just like any other video out here. Never enough info.

Not saying it IS a battery/coil, just pointing out two ways it might be fudged.
Look at his other video he has posted of a homopolar motor.... same size,style as the top of the pendulum.  Might be the reason to have 2 magnets on the top levers (one on top and bottom)... so the coil inside the pendulum top can repulse against the top lever magnet.
Just some thoughts... not saying it is.
More info, details, vids etc. would be required.....

Again, IMO the force needed to move the upper magnets levers and slides is more than the kick provided by the lower magnets.
