magnetic field around ionic conductor is shielded by the plastic tube.
This demonstration shows one of physical effects of the passage of an electric current, namely, an electric field.
As far the mobility of K species (0.000670) is quite the same like mobility of chlorine species (0.000678), their opposite movements will have as result a null magnetic effect (fig. 2). It is simple and straightforward as plus 2 and minus 2 gives a null result. As consequence there should be a magnetic field around metallic part of circuit but not a magnetic effect around ionic portion of circuit.
Quotemagnetic field around ionic conductor is shielded by the plastic tube. Wow! What plastic are you using? Can I get some to shield my MRI machines? No. The ions move in opposite directions because they are carrying opposite charges, so the net current is in the forward direction: a positive charge moving left to right is equivalent to a negative charge moving right to left. Same applies to the sulfuric acid transient you mention later.
"The electric conductivity of an electrolytic solution is not as great as that of a metal. Therefore, the voltage applied between the electrodes must be greater then that applied to the wire, in order to produce a similar electric current in the two conductors. In spite of the higher voltage, the current in the solution is likely to be only a tenth of that in the wire. "Tbh as with your other discussions, your words show your lack of understanding of electricity. V=IR -> the more resistance the lower the current for a fixed Voltage. So its not 'inspite' of the higher voltage its 'because' the conductivity is significantly lower in the solution than it is in the wire. Magnetic field density is directly proportional to current density (with mass/charge density being 3 orders of magnitude greater in ions) you would have to be looking at much larger voltages to achieve the same magnetic fields.. so my interpretation is.. you are not generating a large enough magnetic field to be detected over that of the earth.
I was pointing that response of ionic conductor is delayed and less evident when you use a entire tube instead of a section .
Ions moves in different direction and an electric current goes forward.
You should really read the content of posts before thinking you are right.the Magnetic field density is directly proportional to current intensity the current density is metals is several orders of magnitude higher than the current density in solutions (electrons have significantly less mass than ions, so the charge density is MUCH higher) To get a similar magnetic field generated by the solution you would need orders of magnitude of current to achieve the same magnetic density.
