What type of conductors are being used in the coils made of heavy wire?

In the construction of coils made of heavy wire, copper is the most commonly used material due to its excellent electrical conductivity and relative ease of handling and shaping. Copper has a high conductivity, making it ideal for transmitting electrical currents efficiently with minimal loss. For applications requiring even higher performance, such as in high-energy physics research or in magnetic levitation transport, superconductors might be utilized. Superconductors are materials that can conduct electricity without resistance when cooled below a certain critical temperature. However, their use is specialized and not as widespread as copper due to the complex cooling systems required to maintain their superconducting state.
