Yet another, free, all magnetic idea.

You've got alot of cool ideas, and your drawings/diagrams are unmatched in this forum.
What drawing program do you use?

So these ideas are related to the Howard Johnson gates? (N ATTRACTS N into gate etc)

I like the 2nd design better....

What is the proposed shielding material?
Have you tried any of these setups?
Rather than the magnets moving on a rail (high friction) , afix them to a wheel?
The wire loops drawings need to be modified as the fields are different than the static drawings?
Is the theory the exit force/push is greater than the wall/sticky spot of the entrance field?

So lets do a proof of concept. Whats the simplest way to do this ?

Make the mags from iron blanks[for the donuts] or electro Mags

Its not going to build itself

From the brickyard!!

Lightwave 3D.
I have past experience with it.

It started from a thread about.
The magnetic vortices of HJ don't make sense to me,
so I used my own understanding of magnets.

I like the 2nd design better....

What is the proposed shielding material?

Any good enough shield should do.
The higher the permeability the better? maybe.

Have you tried any of these setups?

No.

Rails are just to simplify the concept.
You can use w/e is best for you.

The wire loops drawings need to be modified as the fields are different than the static drawings?

Not really. this is how the perfect needed magnet would look like. Namely a radially magnetized magnet.
But since they are very rare. You can use two ring magnets in repulsion to kind of simulation one radially magnetized magnet.
But the current loops simulate a true radially magnetized magnet.

Is the theory the exit force/push is greater than the wall/sticky spot of the entrance field?

Without the shielding the sticky point will kill of the energy gains from the push and pulls.
The shielding is very important.

Easiest setup to play around with is the electro magnet setup (unless you already have all the material for the first design).

What you need:
1) A lot of wire.
2) A thick ferromagnetic tube/pipe.
3) A strong cylindrical magnet.

How to build it:
1) Wind a lot of wire like illustrated. Wire should be wound between the outer and inner diameter of the tube.
2) Do the same for the other side.
3) Build a rail that goes through the tube
4) Attach (neo) magnet to rail.
5) Make sure current will flow in opposite directions in the two windings.
6) Power on power.
7) See magnet jump in the gate.
...
Pray to god it gets shot out.

Notes:

Make sure inertia is also part of the experiment. Meaning experiment with different weights attached to your moving magnet.


Some disadvantages:
1) Induction of the loops.

Can be toned down by using loops on the perimeter (illustration will follow.)

2) Eddy currents.

Can be controller by using ceramic non conducting tube material...or
ring laminates stacked on each other to form a tube.

And it shows!  I've got trueSpace7.6, but have never found the time to learn it....

MuMetal for example?  And rather thick as the field needs to be canceled as much as possible.  Thereby the drawing with the 'rotor' mags having shielding as well may offer a better chance of exit?
