Magnetic Susceptibility: Gold's magnetic susceptibility is approximately -3.4 x 10^-6, demonstrating its poor response to external magnetic fields compared to positive susceptibilities found in ferromagnetic materials. Lack of Magnetic Domains: Gold has no domains like ferromagnetic materials, with their aligned magnetic moments.
