Kind: research · Impact: low

## In brief

- Ovcharenko and Podolský present a spacetime describing a rotating, charged black hole immersed in an external magnetic (or electric) field.
- The external field is oriented along the black hole's rotational axis.
- The solution is characterized by four physical parameters.

## Why it matters

It offers an exact theoretical model of a rotating charged black hole in an external field, which can serve as a reference case for studying black hole physics in such settings.
