Magnetic flux control idea

[shylo]

So if we have a steel rod positioned beside a magnet, the lines of force are concentrated towards the steel rod.
Now if you bring another steel rod to the opposite side are the lines now divided between the two?
Meaning the attractive force is now half?

Not all the field goes through one steel rod. Rest of the field loops right back throug the air.
Adding one more rod, it willl guide some of the field too, but less density through each rod. Because one rod weaken the the field elsewhere. If you could count field lines into 10 lines. Then maybe 5 of those goes through a single rod. Adding one more rod, maybe 4 lines goes through each of them, leaving 2 lines left that loops directly through air.
I hope this explanation makes sense


So the widest part of my shield guides most of the field, while the hidden rod inside gets "nothing".
At the narrow side, the rod dominate the field, while less goes through the shield.
However, lots of the field goes through the wide side, leaving less on the narrow side.
But if the magnet is long, the field will "hit" the shield perpendicular to the wheels, and that, I suppose, will leave a uniform field through the whole diameter of the wheel.

I quote you again.
In my previous reply to you, I explained two rods on each side with no other magnetic objects nearby,
However, in the wheel I've designed, I assume that the narrow end rod is more magnetic attracted than the wide side rod because the stationary shield at the wide side is picking up more of the field than the narrow side. The wheels itself is also magnetic attractive, and that is the main reason why I'm confused about how equilibrium can occur.
If it's the case that one side of the rotating wheels, including rods, is more attractive on one side than the other, I will probably be killed by Big Oil . However, I want to live my life, so I hope my assumtions isn't correct.
I will do some more simulations on this also, but FEMM isn't considering the magnetic field that goes "in and out" of the computer screen, only those in plane with the screen. Also, Femm cannot simulate an object that is wider on one end than the other. The defined depth of the model is fixed to the same depth all over the place, on every object. Iron, magnets, air, or what not.
Therefor, FEMM is pretty much useless to simulate a model that have magnetic fields in three dimensions. So I must try to make a simulation, or several, for it to make sense. However, the best "simulation" is building the thing and get it over with.


Now, I'm resting on a hotel after 7 hours driving. Some dinner now, and I will start simulating more while am not at home and able to do any work on my model.

So the magnetic pull never weakens no matter how many avenues we give it?
As long as they are of the same orientation?

I would say that the magnetic pull on one single steel rod weakens if you introduce another steel rod, but not as much as half. Both will have a combined pull greater than one single steel rod, but not double the force.
