Mainly metals. Silver is the best but copper is nearly as good and a lot cheaper. Aluminium is about 40% worse but is popular for overhead cables because they are lighter.
The electrical trade is one of many trades that use conductors for projects.
Each telephone line uses only two conductors.
Long, spiked, rigid conductors are usually used as ground rods.

Metals are conductors.

The stick musical conductors use is called a baton. It helps them keep time and guide the orchestra or ensemble during a performance.
Personally, I use "Hold"...

'Bundled' conductors describe a line in which two or more conductors are supported from the same insulator chain. In the UK, 275-kV transmission lines typically use two conductors per line, and 400-kV transmission lines typically use four conductors per line. The purpose of bundling conductors is to spread the electric stress on the conductors (e.g. for four conductors, the same amount of electric flux will be 'shared' between the four conductors, rather than concentrated on the surface of one conductor).
Without conductors, electrons do not flow where you want them to flow. An electrical circuit is a flow of electrons.
It is electromagnetic induction.
