Direct numerical calculation of interactive effects among Stoner‐Wohlfarth particles is presented. Hysteresis behavior of both individual grains and the bulk sample are altered significantly by magnetic interaction between the individual grains, causing clustered single‐domain particles to behave like multi‐domain particles. Reversible interactive effects and tangential interactive fields are important and should not be neglected in future modeling.
