Question

1) Is the electromotive force of a cell a kind of force or something else?
2 ) A metallic current conductor is carrying current. Is it charged?​

Answer 1

1. Electromotive force, also called emf[1] (denoted and measured in volts), refers to voltage generated by a battery or by the magnetic force according to Faraday's Law, which states that a time varying magnetic field will induce an electric current.[2] Electromotive "force" is not considered a force, as force is measured ...

2. It's neutral. A wire/resistor cannot store charge. Carrying current simply implies that charge carriers that already existed in the metal wire is in motion. And every charge particle that leaves the metal from one end, is compensated by another entering the wire through the other end from the battery/voltage-source.

PS: Metals are rich in charge carriers. Existence of charge carriers is no reason to think that the material possess charge. A material possess charge, only if an imbalance in +,- charge carriers exist. In metals the +,- charge carriers are balanced, hence doesn't possess any charge in the first place.  And when its carrying current, the charge carriers that are lost from one end is replenished through the other end of the wire retaining the +,- charge balance.

Answer 2

1. Electromagnetic force of a cell is the maximum potential difference across the terminals of a cell when no current is flowing in an external circuit. It provides the motive force to drive the current through a circuit. Is is not a mechanical force.
2. No, the current in a metallic conductor is due to the flow of free electrons in a definite direction. At any ins.tant the number of protons in the conductor are equal to the number of electrons. Thus, the net charge in the metallic conductor is zero.
