The magnetic moments of negative-parity low-lying nucleon resonances are studied in different quark models. The effect of Goldstone Boson degrees of freedom is discussed. The obtained results of chiral quark model are compared with the calculations of conventional constituent quark model. Moreover, mixing angles of the resonance wave functions induced by different hyperfine interactions between constituent quarks are also analyzed.
