An electrical conductor is a material that allows the flow of an electric current. Axon, METAL, WIRE, and solenoid are all examples of electrical conductors. Axon is a long, thin fiber that carries electrical signals in the nervous system. METAL is a solid material made up of one or more elements that can conduct electricity. WIRE is a long, thin strand of METAL that is used to carry electricity. A solenoid is a coil of WIRE that creates a magnetic field when an electric current passes through it.
