| Magnetism is ubiquitous in the Universe. However, the magnetic properties of stars are still far from being completely understood. Recently, tremendous progress has been made due to large-scale spectropolarimetric surveys and advanced modelling approaches. In this talk, I will present evolutionary models of massive stars that incorporate magnetic field effects. I will highlight how these models differ from previous non-magnetic models. I will discuss the impact of massive star magnetism, for example, in stellar age determinations, as well as the physical characterisation of stars. I will conclude by outlining possible future avenues to gain further insights into the nature of stars. |
