Levitation using earth's magnetic field - "electric propeller".

I have idea how to levitate using weak earths magnetic field.
It is something like electric propeller - magnetic field line booster.

There is 3 wires (in this case). With no current in wires all is standard, no levitation.

1.SEQ: First wire have current, 1.field line going down
2.SEQ: First a second wire have current, 1.and 2. field line going down
3.SEQ: All wire have current, all field lines going down.

Restart sequence: All wires without current.

Again 1. SEQ to "sucking" another field line from above.
2. SEQ ...
3. SEQ ...

Restart ...

Only condition is that sequences must be count quicker against magnetic field lines restoring.
Is this possible ?

Field lines are not countable, and they are not objects that will "push" anything. Anyway, you get a force between cables and a magnetic field, so that is not the main issue (ignore the "sequence", that is irrelevant).
A cable with current in the proper direction will see a force upwards, but where is your current return? You cannot simply create charges at one end and remove them at the other side. With a current return, you get a force downwards, and both cancel.

The vertical component of the magnetic field can be used in that way - make a horizontal ring with a strong current, and you get a force upwards everywhere. The magnetic field of earth is too weak to lift that thing, however.

Return will be in shielded area.
Something like "band saw" where blade will be wire (without movement of course).

Next idea can be self charged power sources with + and - potencial at the end of wires.
Something like charged skies vs earth during flash.

That does not work.

Throwing in random buzzwords is not an "idea".

Why shield does not work ?

"Why does magic not work?"
There is no reason to expect something to work unless you have a specific mechanism how it is supposed to work.

Shielding can change the shape of the field, but it cannot completely "remove" it. You still have the field in the setup and it has to cross the return wire somewhere.

The idea of those cables is to get the same influence on both directions, so their contributions cancel. They are great if you have a closed circuit in them (both directions in the same cable), something that would be useless here.

without a lot more working info, that drawing is meaningless

Instead of arguing fruitlessly about this, why not accept that your proposal is a non starter. After all, you did come to a forum of relative experts so shouldn't you accept what they're telling you?
To argue against them successfully, you need to spend a few years actually learning the subject.

Anyone who thinks they've come across some magic form of propulsion / energy source / cure for all disease should first ask themselves why it is not available in the shops.

This would violate charge conservation.

Unless you have some electric connection to earth... but then it is a simple current loop, that is easy and does work. The StarTram is a huge proposed structure that could work like that.
