Magnetic effects around electric currents and absurdities of modern physics

It is assumed by actual physics that an electric current traveling along a
conductor generate a magnetic field around conductor too.
But, material science makes a clear difference between electronic conduction and
ionic conduction. The model of classical electromagnetism is based on electronic
conductors and their effects.
What's happened in case of an ionic conductor?

The absurdity of ,,Maxwell equations" extension to all electric and magnetic
phenomena does not need any comments. The plasma domain is a completely unknown
field for actual theoreticians and sure Maxwell equations are ruled out in this
field.
