GENE-3D is a code that is capable of simulating gyrokinetic plasma turbulence in stellarators globally (Maurer et al., Journal of Computational Physics, 2020). It has recently been upgraded to an electromagnetic version, expanding the variety of turbulent features that can be studied with it. In this work, we present the underlying algorithm, together with verification studies against the established global tokamak code GENE (Jenko et al., Physics of Plasmas, 2000). Finally, we present a first application to stellarator physics, by investigating the influence of finite plasma-β on ITG turbulence in Wendelstein 7-X.
