Fast radio bursts (FRBs) are millisecond-duration coherent radio emissions originating across extragalactic distances. Identifying the progenitors of FRBs remains a critical question in astrophysics. Recently, a subset of repeating FRBs has been associated with persistent radio sources (PRS), providing a unique opportunity to study the immediate environment of these enigmatic bursts. Magnetars are considered strong candidates as FRB progenitors, and their association with PRS offers a valuable platform to test this hypothesis. In this talk, I will explore the magnetar characteristics required to replicate the observed properties of PRS, emphasizing the role of internal magnetic fields as a critical factor in powering these sources.
