Question

In the lab frame is this current carried by ion or by electron or by both

Answer 1

Explanation:

Lab frame with two wires carrying current in opposite directions. As in metal wire, the current is due to the motion of negative ions (electrons) only.

Answer 2

$\Huge{\red{\underline{\textsf{ANSWER}}}}$

★ The current is carried by electrons in lab frame .

Explanation:

An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte or both ions and electrons such as in an ionized gas.
