The baryon magnetic moments are studied phenomenologically by introducing the parameters r and for the mass ratios m_u/m_d and m_u/m_s respectively and the mass correction parameter ε for the mass of diquark compared with the sum of quark masses. We fit the experimental values of baryon magnetic moments using two sets of values for r
and ε. The theoretical predictions are in general agreement with experimental values. The fit is better with m_d<m_u. Although the magnetic moments μ and μ are low compared with experimental values
the results show improvement over various theoretical predictions.
