[@PurtyPurple]

​@adoramay9410 Energy is not being added. Rather, general relativity says that the orbits of the planets are actually following "geodesics" (fancy word for a straight line in curved geometry). So the planets don't need energy to orbit. The mass of the sun curves spacetime, and the planets (like everything) naturally want to go in a straight line when there is no external force acting on it. It just so happens that due to the curvature the "straight line" is an orbit.

The force of gravity was already beaten by the magnets to get the fluid up there, it would obviously therefore be too weak to pull it back down.

Best explanation of why this doesn't work I've seen. I know you're basically saying the same thing as what the video said, but I like how you said it better by speaking in terms of what we would expect to complete the loop (gravity)

[@AlexM645]

it's only the friction of the fluid against the chain that impedes the movement. If there was an equal ammount of fluid going up and going down, it could be modelized by a sort of wheel (held together by viscosity) and it could 'rotate' with its inertia. It's not truly a gravity problem

[@joshbridges8410]

It climbs through capilarity force and there is nothing to climb on at the end.

[@CuSolais]

Everyone in the comments just "what if he had a pointed stick!" Lol. Friends the energy required to pull it up the chain will always remain the same. So it will never pull more up than it can hold. Even if the end magnet was weaker it would still just make the next strongest magnet hold the majority of the mass. You would actually see the bead around it be bigger than the bottom one. This is clear by even dipping the end in the beaker it did not take more than it can hold. The flow cannot exceed the energy the magnets exert to pull it to it. I think its far more interesting the first example showed the magnets create a siphon effect and half filled the other beaker.

[@vituperation]

Right? Using the magnets to induce a siphon was cooler. With an electromagnet, I imagine you could turn a siphon on in a ferrofluid a lot easier than with a pump. No idea why anyone would need that, but it's cool!

[@reznovvazileski3193]

Yea I figured the magnets would just suck up as much as they need and then stop :') Magnets aren't a siphon, they're magnets. The reason ferrofluid is running up there is because it's a metal in a magnetic field large enough to overcome gravity on exactly that amount of that metal. Whenever the field is saturated the process just stops dead in its tracks because the magnets can't pull up any more, and it won't drop anything because they can't pull any less either being permanent magnets.

[@rodschmidt8952]

and... they won't drop the drip because they're magnetically pulling it back up

[@skourpi142]

This idea was similar to an earlier idea for perpetual motion, however it used strong cohesion instead of magnetism. However, the problem is the same. Water got to the end, and didn’t drip down because it had already climbed up against gravity and would just stay in the tube that had helped it climb up against the force of gravity.

If it is able to lift the fluid up then that means it is able to fight against gravity, meaning it won't drip.

[@AlexM645]

it would drip if there was a flow of fluid, but there isn't one due to friction. The tip can only hold so much and if there was a perpetual motion, the mass of fluid at the tip would stabilize to it's exact 'dripping point' so that over time, it doesn't hold less or accumulate fluid.

You should try putting a non magnetic surface (like a straw or something) to connect the end of the chain back to the liquid in the beaker.... That might do it.

[@Shoteaux2]

then it wouldt climb up in the first place

[@juliavixen176]

It will stop flowing when it reaches equilibrium... (like it did in the video for example). The liquid is going to flow until it is at the lowest potential energy, and then stop.

[@damegataco]

@@juliavixen176 the reason I thought it might possibly work is because the straw won't allow it to grip onto it and thought it might not be able to create a stable flow from where the balls end to the cup belos to create a path of fluid between the two held in place by the magic force... I could be wrong, but it would be interesting to see.

[@damegataco]

@@Shoteaux2 1 I think you misunderstood what I was trying to describe... The straw/rod/w.e would go in between the liquid and the end of the ball chain while the ball chain would still be in the same position. That way it would build up on a surface that's not magnetic and possible flow down it. I'm guessing that's not what will happen, but it would still be interesting to see.

[@vituperation]

​@@damegatacoAs I understand it and if I'm reading your comments correctly... You could create an arch filled with fluid, but once it settled, you wouldn't get a net flow through the tube. The energy of the magnets would just help siphon the fluid up then it would reach an equilibrium. Imagine a tube filled with water and both ends dipped into the same bucket of water. It's filled with water and appears to be fighting gravity, but it's not flowing (other than convection, Brownian motion, and all that). In the case of the rod, you'd get as best as the cohesion of the fluid to itself and/or the rod could offer against the magnets and gravity. If the magnets were weaker to let the liquid drip down then they wouldn't be able to lift against gravity in the first place. I don't feel like I wrote that very clearly, but hopefully some part of it makes sense.

The calculation of the delta in potential energy gain, in ratio to the thermal energy (joules) applied, showed over-unity. Another generator dips strips of nitinol alternatively in hot and cold water and the generated motion is captured in a teeter - totter motion. Cheers!

[@_ninthRing_]

It looks like you need to have multiple chains feeding into a single (non magnetic) drip point. That way, the mass of that drip becomes big enough for gravity to overcome the attractive force of the magnets. This would feed a damn slow cycle of magnetic attraction vs. gravitic attraction. Put the whole contraption inside a bell jar (to prevent the ferrofluid from evaporating or coagulating) with a camera on it to count the period & frequency of drops over the next few years...

[@durgaprasads8003]

But then it won't climb due to gravity

[@juliavixen176]

Gravity won't overcome the magnets on the dangling end, any more than gravity overcame the magnets on the other side in the fluid. The whole thing is in equilibrium and at its lowest potential energy level. It's not going to move.

[@vituperation]

^ this. If the magnet can pull the fluid up, it can pull it down with equal force. One leg of the arch isn't going to flow any more than the other leg. One side of a magnet isn't pulling any more than the other side.

[@pipeliner4029]
