Magnetic flux control idea

[Low-Q]

The first obstacle I can think of is similar to the problem with the buoyancywheel in the video (First post).
Since the rods is angled relative to the wheels, one side of them (rear side relative to desired rotation), is more exposed than the other.
However if this is the case, the rods should have torque around its own axis that is going in the same direction as what I want the wheels to do. These forces probably cancles out.


The second obstacle is the ferrofluid under magnetic impact. What happens with the ferrofluid close to a magnet, is that it gets "harder" for objects to enter. The pressure in the fluid increase.
However, the narrow part has very little solids to enter, and more solid to exit at the wider part. Meaning that the buoyancy is greater at the wide side.


The third obstacle is a result of the first and second obstacle. Between the wheels, there is more surface area in front of the rods than behind them. The pressure from the ferrofluids impact with magnetism will push them backwards at the bottom. This will probably be counterforced by buoyancy differences in the second obstacle and the magnetic attraction from the narrow side.
However, if the rods weren't magnetic, it would not be attraction from the magnet, but the pressure caused by the magnet at the bottom would still be there and pushed the rods backwards.


In sum, these three obstacle is something I have been thinking of, and I assume none of them have any driving force in one or the other direction. What I got left is the difference exposed rods outside the wheels - at the narrow side versus the wide side.


Therefor I got to build it to see what is actually going on. Energy MUST somehow be conserved, right? What if it's not?

Three out of six rods isn't magnetic

I have decided to cut the three "working" rods in half. They are too long anyways.
Here is more pictures.
I am printing out a bellow in flexible material to seal the space between the wheels.
Then I put ferrofluid inside.

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 Vidar,

You are in a respectable process that I am not criticizing at all. Unfortunately, it is clear to me that the underlying physics that you are missing will prevent you from succeeding.
Sorry to sound really pretentious, but if you see a child trying to make a jigsaw puzzle, and either you know there are missing pieces or he has mixed them from other puzzles, you know he can't succeed, wouldn't you tell him?
I'm not negative, I'm positive: you do a work of remarkable competence in mechanics but not in the right direction.

The movement of permanent magnets is a matter of magnetic potential energy, as weights under the influence of gravitational potential energy. Magnets move to the region of least potential energy.
The force on them is conservative, this means that the work between two points does not depend on the path but only on the potentials of the start and end points.
For the magnets to move, there must be a magnetic potential difference between the starting point and the end point. In a cycle, the starting point is the same as the arrival point, there is no potential difference, so there is no cause for magnets to move between the two points even though they have to go through a lower or higher potential point between the two. A ferrofluid doesn't change anything, it's also submitted to this principle of magnetic potentials.

Thanks for your input. The missing physics is the very reason why I want to build this. I already know it wont work, but I need to know why. Practical experiments never lie, and is the best way to learn the truth
