I fear your model is missing the nature of induction. A varying field induces voltage in a conductor loop, shielding a single wire has no effect at all. The shield must enclose the loop.STP doesn't help here because I only got 1 wire.
Well there is no distance to the interference, as I said the wire goes through a core, i can only make a hole and wrap some shielding metal around the wire so that the flux warps around it without directly traversing it, that is the idea.
I strongly doubt. Ultimately shielding a single wire increases its impedance but not induced voltage.he is talking about magnetic material to shield the wire - this will of course work.
The flux is parallel to the loop not perpendicular to it, and it's equal on both sides of it. So there can be no induction in the loop as total because field lines are not "looping" through it like they do in a coil wrapped around a transformer core.I fear your model is missing the nature of induction.

What are you shielding at all? Either there's no flux through the loop, then you don't experience induction. Or there is some, at least residual, flux, then shielding the wire won't help.The flux is parallel to the loop not perpendicular to it, and it's equal on both sides of it.

Now I have bought a permalloy metal foil of 0.1mm thickness and my idea is to create a tube of that foil where multiple layers are wrapped around it + add some copper foil tape on the outside.
Who said I can't use coax, I can use pretty much anything just that it has to be well shielded.too bad you can't use coax.
