Abstract
In quark potential models, two-body current contributions to baryon ma gnetic moments arise necessarily to satisfy the continuity equation fo r the electromagnetic current. On the other hand, the naive additive q uark model predicts the experimental octet magnetic moments to within 5%. We demonstrate that consistently derived two-body current contribu tions to the octet baryon magnetic moments are individually large, but tend to cancel each other globally.
