flux laminator

Nice flux gate 

from my own personal experiences in this area, what generally happens is the paramagnetic strips/ring/ect pulls TOWARDS the magnets regardless of polarity, and will get stuck in the spot where the flux lines are most dense.

Ah yes, I use to think flux scaled with force to. But, I'm exited to inform you it's wrong. Flux is the biggest under 180 degrees while force is the biggest under 90 degrees. The thing is: the forces of both poles can do work in one and the same direction. But: they can only~ever induct as much flux as their difference. It will either bake a north or a south pole into something or non at all.

For doing work you never have enough poles, but if you want to induct a field you need to use one kind of poles.

So the strip is getting magnetised by a single pole at the top, then the strip is pushed and pulled but without inducting much flux into it. I'm under the impression the strips don't magnetise instantaneously so the forces pulling the strip out of the flux should persist a bit longer as the flux inducting into it. The size of the magnet and spacing of the strips should keep the number of strips under it almost constant.

The apparatus should spin fast enough for the strip to move into a repulsive position before this flux is fully inducted into it. By the time the flux in the strip ramps up far enough to start repelling one side of the other magnet the strip has already moved close to the domain wall, the push is now much bigger when leaving the wall as that what was opposed when moving into this position. The pushing pole should have pulled the strip backwards while repulsion was building.

The question is:

Can a pushing and a pulling magnet pull a magnetised strip out of a pulling field. If they are all 3 the same size the answer seems obvious? The (by pushing) complimented pulling magnet is going to win the rope pull? The push will only collapse when the strip has successfully moved away from the lone actuator lodestone inducting it's flux therein.

A huge difference with a flux gate is that the gate doesn't use magnetic forces. I thought Ecklin Stationary Armature Generator was quite a hip flux gate.

I envision this push/pull thing is also the big trick to use in a pulse motor. You get push, pull and a lack of back emf! What more do we want?

The magnetic field is not opposing the current.

Then use an air coil to extend a permanent magnet, just like those strips in the device here. But I don't like all the wires, so maybe we can make it without? lol

the magnets should be attracted to the steel strips regardless of polarity. You can try this experiment to verify it:

The magnets will still be attracted to the steel regardless of the other magnet's presence.

Here,



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.

The magnets will not be attracted to the steel until the steel has a minimal thickness.

Now I don't have the stuffs to test this theory.

If it hasn't been tested I wouldn't yet call it a theory.

Anyways, it would be nice if magnets worked like this, however I agree with sm0ky2 that the magnets should be attracted to the steel strips regardless of polarity. You can try this experiment to verify it:

The magnets will still be attracted to the steel regardless of the other magnet's presence.

the other magnet is not necessary to create this effect. 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.
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, 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.

2 repelling magnets repulsion practically disappears when you hold the shield in the center. But move it  slightly towards one of the magnets and it will be attracted and repelled. I'm not sure in what proportion tho.

It does show how a magnetic shield can be moved in and out of position by moving towards the magnet. Repelling magnets equally far away from the shield give much less repulsion. Even if the extra push and pull end up equal in size we still get a magnetised strip that we can turn on and off.
