In previous work we have studied Lorenz type differential equations with topological methods and dynamical systems. We found chaotic fractal structures, and relations between the length of a period and the following. We also found a relationship between the intensity of the toroidal magnetic field and the length of the previous period. That study was motivated by the need for improved predictions of the large-scale magnetic activity and solar cycles. In this work we try to describe and explore small-scale turbulent solar magnetic activity using SDO and SOHO data. Dynamical systems are again applied. Braided structures will also be studied. The first results will be presented. This study is motivated by the need for improved predictions of small-scale solar magnetic activity and of coronal loop evolution resulting in solar storms.
