Abstract

In this study, the source of the black bounce is discussed in the context of $f(Q)$ theory. A body of research has been dedicated to the study of symmetric black bounce solutions that are generated by a combination of a scalar field with a non-zero potential and a magnetic charge within the framework of non-linear electrodynamics. As exact solutions are not obtained, the metric functions of Simpson-Visser and Bardeen type of black bounce are studied in the field equations. black bounce solutions are obtained by violating at least one energy condition for the Simpson-Visser and Bardeen type for an ordinary scalar field in $f(Q)$ gravity, which is only achieved by a phantom scalar field in general relativity.
