Magnetic flux control idea

Here is a video showing the friction.

That is gonna result in one big mess.

Big mess, and hard to turn, weak ferrofluid, and weak steel rods. I came up with a similar design without ferrofluid that I will test with iron filled 3D-filament.
In the images below, I have two green wheels, one red shield. This red shield is fixed and stationary. Everything is printed in magnetic materials.
I might print the blue rods as well, but I already have magnetic (weak) steel rods already from the ongoing experiment.


The red shield, as well as the wheels, takes up magnetic fields. The thought is alike the ferrofluid experiment, that the wide side takes up more magnetic fields than the narrow side.
So wide side will ofcourse be more attracted to the magnet than the narrow side.
The steel rods is as usual more exposed at the narrow side, but hidden inside the shield on the wide side.


This experiment is much smoother. The wheels can turn freely with very little friction.
This will be a great benefit when I check how the rods behave in the magnetic field as I turn the green wheels by hand.
Also, I can test one steel rod at the time without ferro fluid leaking out - because it will not be ferrofluid in it.
Another benefit, is that without the ferrofluid, it will not be areas which harden or compress due to the magnetic field.


A narrow airgap between the wheels and the fixed shield will avoid friction (last image)


I think this experiment will be very similar, given the magnetic properties.


It will be friction somewhere, but that is not important.
Most important is that low friction is beneficial in view of the experiment's goals.

Complete structure.
The wheels are also made from magnetic material.

Gabriel Kron said that Maxwell's laws break down, if the system has rotating parts like coils. Maybe angled magnetic fields do the same like in this machine?

He also said that if system theory shows that a system appears to have a negative resistor in it, the system will behave like there is negative resistor there. So the goal is not to find a negative resistor, but to build a system that appears to have a negative resistor in it. Making something that is not there to actually manifest the effect of such a thing. So in effect maybe you cannot build a negative resistor, but you can gain the effect of one
