For cylindrical black strings, NED Lagrangians with a Maxwell weak-field limit cannot produce regular purely electric or dyonic cores; regular magnetic Bardeen/Hayward analogues exist but violate causality near the axis.

Tidal forces in the Simpson-Visser spacetime produce Roche radii for stars that depend on observer type and regularization, with some disruptions occurring outside the event horizon for supermassive black holes.
Dymnikova black hole geometry is realized via Maxwell sources in unimodular gravity with radially dependent Lambda, producing a regular electric field from a localized charge distribution that has zero net asymptotic charge.
