flux laminator

[gaby de wilde]

Now the steel strip is not attracted to the magnet at the right. It's trying to induct 2 different fields at the same time. I just place a strip on the domain wall then move another magnet over the strip. As soon as the slightest field is inducted into the strip it forcefully moves off the wall.

If you induce a field along the domain lines such as in this picture, the steel will repel itself to one side or the other, because it does not want to have both sets of flux lines cutting each other like that, they would rather travel in the other direction towards the magnetic poles.

Not entirely, the domain wall is easy to find. The opposing induction cancels it self out.

In actuality if you were able to hold the magnet Precisely ON the line there would not be a force in either direction as they would balance out,

the inducted flux from the right balances out close to zero.

If the magnet at the left would not be there the other magnet would ignore the strip entirely (try it)

BUT BUT! the moment flux IS inducted into the strip(by other means) the forces from the flux at the right do compliment each other.

You understand?

The magnet doesn't induct a field anymore but it does still have that field of it's own. So when we use other 3rd party means to induct a field into the strip THEN both of those fields can interact. They don't interact in a contradicting but in a complementary fashion.

The big discovery: The fact the magnet doesn't induct a field on it's domain wall doesn't mean it doesn't have a field of it's own. The moment we create a pole on this spot it will absolutely interact with the other poles.

A metal strip does nothing but holding a magnet on the domain wall creates torque.

but in practice you cannot find a line that infinetesimally small so you are more to one side than the other, which pushes the steel into either the N or the S field.

But it's easy to find, and it's easy to see how attraction drops off over 90 degrees. The induction and the magneto interaction are 2 different things you see? The interaction demands a field inducted into both bodies, but there is no rule that says it has to induct this field it~self. Any inducted field will do?

lol, I don't know how to explain this? I'm doing a horrible job? What do you think I'm talking about?

wha ti am saying is, if oyu have a free moving ferro-magnetic material that approaches a magnet on its domain-line, that line is infinitely smaller than the physical object you are approaching it with.
in fact, you must apply considerable force (per flux line) to hold the object "on" that line. it wants to pull to one side or the other.

WHICH SIDE??  that depends on which side of hte line you are holding it on, you are ot holding it "on" the lline.

you cannot, not with your hands, and i doubt we could achieve this with an exact measured line, and computerized steppermotors..  especially if the mol count on one half of your metal object is greater than on the other. (mass dispursion) - which cannot be felt/seen without extremely sensitive equipment.

Whne you induce a secondary field into the ferromagnetic object, on the opposite end from the original magnet all you are doing is setting up opposing polarities within the length of the object.

If your secondary magnet is North side facing the bar, the end of the bar becomes south and tries to make the other end of the bar N.  Now if you are near the center of the poles of the first magnet the flux lines are not very dense, it may take a stronger magnet or a longer bar to overcome the effects of the secondary magnet. Once you get it arranged where the primary field actually effects the bar, then all you have is a S pole magnet near the center of the poles of the first magnet.  if you are slightly to the N side it will push to the S, if you are slightly to the S side it will pull towards that end.  If the secondary magnet produces stronger flux lines at the end of the bar that is nearest the first magnet, then the bar wont feel much effect at all. (assuming the bar is not physically attached to the second magnet.

It's irrelevant, the strip moves over the domain wall from one pole to the other, losses are roughly equal to the gain. IT becomes a pole for a moment. That's all. Anywhere near the wall the inducted fields subtract but the forces are actually doubled. We get less induction and 2 times the magnetic force there.

you can just use a solid donut and hold the other magnet behind it it appears. Laminated would be better of course.

One question, on your definition of "laminated" do you mean laminated as in having layers of steel strips or, "laminated" as in you would coat the steel with a plastic or other material.

I was referring to just strips, I have no idea how a solid donut or coated strips would preform. I'm sure putting some coating on the strips is a good idea to try however.
