Magnetic flux control idea

[Low-Q]

Ok I understand your design, but I don't see why it should rotate.
It will just find balance and sit there.
The wide part stays at ~90deg. and the narrow at~270deg. why should it rotate?

That has crossed my mind too, but the wide part stays at 0 ° and narrow part stays at 180° - all the time. The wide part isn't falling down to the bottom at 270°, and the narrow part isn't rising to the top at 90°. The ONLY thing that goes around is the flat disc wheels and the steel rods. The wheels is just acting as walls to keep the ferrofluid inside.
However, Im not claiming that this will work , but my idea is that the narrow part exposes approx 90% of the moving rods/parts to the magnetic field. At the bottom approx 50% is exposed. At the widest part 0% is exposed to the magnetic field.
Since the ferrofluid is stationary and fluid, there is no torque in this part at all. Yes, the wheels are turning, but the ferrofluid doesn't need to turn with it. However, its viscosity will finally force the ferrofluid to rotate with the wheels and rods, but that is actually not doing anything.


Since the ferrofluides shape and orientation is stationary and liquid, and the only moving/rotating magnetic parts that "changes size" is the steelrods, the stationary ferrofluid will dominate and cover for the magnetic field more and more as the rods moves from the narrow to the wide side. By doing so, less magnetic field is attracted to the bottom steel rod alone, than the field interacting with the rods earlier, closer to the narrow part, and less and less magnetic fields interact with the steel rods from the bottom toward the wide part.


The idea is that the magnetic interaction with the rods is not balanced, but insted imbalanced by attracting the moving rods more on the narrow-bottom side than the bottom-wide side.


I just got some rubber rings that I will put the steel rods through as a seal. I just need to print out a small model of the wheels, shafts etc. I got approx 50cl of ferrofluid left, so the model will be small.
I also expect more of a mess, than a working model, but it is fun to try

I changed my letters somehow?I think you would be better to test and see if the ferrofluid really does reduce magnetic attractionto the steel.Also any fluid will cause friction on the disks and rods.But if you do build I wish you good-luck and look forward to your results.artv

It is a mechanical and magnetic system where no new laws of physics have been claimed in order for it to work. Therefore as it is obeying the laws of mechanics and electromagnetism, it is also describable by a Lagrangian which is fully compatible and logically equivalent to a description by forces, torques and their works. Therefore there is no extra energy. It's as simple as that.

Is this "idea" claimed as a type 1 perpetual motion?
A positive answer implies that the given description of the "idea" is inconsistent for the above reason.

Is not this "idea" claimed as a type 1 perpetual motion?
Then either the "idea" is to tap an unknown energy source (a clue about which?) or the laws of mechanics or electromagnetism are indeed implicitly challenged (which ones?)

Hi there. I haven't claimed anything. I just need to figure out how magnetism "works" on this. I know just as well as everyone else, that overunity or perpetual motion can't work.
This time I got stuck. I do not know what is happening to the device. I don't know what mechanism that counterforce the rotation, except friction. For me, as I write, I have no good reasons to why it doesn't work. I want to find that reason. To do that, I must build, because I can't simulate this.

Hi! You probably hit he B-button above the text box :-)
I have printed out the first two discs. Two more equal discs is in production. These will just laminate the first ones so the rubber gaskets doesn't fall off.


This fluid have a rather high viscosity. It is mostly oil. Friction is an issue, but also when the gaskets slides back and forth on the steel rods as the wheels rotate. The steel rods I'll be using is 304 steel (Almost stainless). They react on magnetism, but not as good as iron. More like the ferro fluid. This will help because I have only strong neodym magnets available, that would probably destroy the device by crunch it together.


I'll start with six rods on this. Few enough to feel how the magnet interact with the device at different positions/small turns. This way I will learn how the ferrofluid in combination with more or less exposed steel rods will work. So I hope the friction is low enough to sense some forces backwards and forwards as I turn the wheel by hand. I can just dream about a self running thing. I honestly cannot imagine it will work with no hands involved. Let's see how the outcome is - good or bad.


I attach a picture of the first discs with small rubber gaskets in them.
