copper in wires is a metal, and like all metals it is made up of atoms bound together. Basically, atoms are made of a nucleus in the middle, and electrons revolving around the nucleas. In all elements except metals, the nucleus doesn't "let go" of the electrons (unless there is a chemical reaction, but dont worry about that for now), but in metals, the electrons are"allowed to go around" to other nucleuses, electrons are allowed to flow around atoms freely in a metal. It is this flow of electrons that is electricity. however a driving force is needed to make the electrons flow around the copper wire, this comes from a battery or a dynamo.

Does electric charges travel only through wire?

There are 2 questions in this : 1: if it is about material... A: No electric charges can also travel through all the conductors of electricity like water, humans, animals, metals etc. 2: if it is about area in which electric charges pass through... A: No, If current is AC then it travels on the surface of the wire, and if the current is DC then it travels through the wire evenly.
