the carbon rod is the medium for conduction of electricity inside the battery
a carbon rod or a pencil used in an arc lamp; also, a plate or piece of carbon used as one of the elements of a voltaic battery.
carbon rod
The top of a battery is called a carbon rod, which is on the positive terminal.
The negative terminal of a carbon/zinc cell is connected to the zinc cup that functions as the cathode. The carbon rod is the anode (positive).
A dry cell battery uses two electrodes made of dissimilar metals inserted in a paste like electrolyte. The container of a dry cell battery is made of zinc which is the negative electrode. The carbon rod in the middle of the dry cell battery is the positive electrode. The space between the electrodes is filled with an electrolyte usually manganese dioxide paste. the paste causes a chemical reaction between the carbon rod and the zinc case.

No, Carbon is diamagnetic.
A carbon rod may be an insulator or a conductor. It depends on which allotrope of carbon we're talking about. Electricity can travel through a graphite (carbon) rod easily, but it cannot travel through a diamond rod. Both graphite and diamond are carbon, but the former is a conductor while the latter is an insulator.
If you look carefully there is a long steel rod which it vertical tot he battery. There is a clamp at the base of the battery that holds the battery down. This long steel rod is attached to the clamp. The top of the rod is shaped to take a spanner (I use pliers on mine). You unscrew the long rod (which is the same height as the battery) and when it unscrews the clamp stays attached to its bottom. Pull the unscrewed rod out, and the battery will now lift out.
No, carbon itself is not magnetic.
