The IMaX (Imaging Magnetograph eXperiment) magnetograph, an entirely Spanish instrument, has revealed where the small-scale magnetic structures that cover the solar surface concentrate. The unbeatable resolution obtained by the SUNRISE mission has enabled the observation of small convective sinks where magnetic fields concentrate, hence reaching magnetic field strengths of up to kiloGauss. The Spanish National Space Program has contributed SUNRISE with the design and development of the IMaX magnetograph through five institutions, namely, the Instituto de Astrofísica de Andalucía (IAA-CSIC), the Instituto de Astrofísica de Canarias (IAC), the Instituto Nacional de Técnica Aeroespacial (INTA), the Grupo de Astronomía y Ciencias del Espacio (GACE) from Universidad de Valencia, and the Instituto de Microgravedad Ignacio da Riva from Universidad Politécnica de Madrid. IMaX has been designed to studying the solar magnetic field with an unprecedented resolution and for several day periods with a stable image quality. This enables to significantly increase our understanding of solar magnetism, its evolution, and its effect on the interplanetary medium
