After a long period with very little magnetic activity, the Sun has started a new cycle. This rise in activity means it is an excellent time to study the Sun, particularly given the outstanding satellite and ground based instruments that are tracking solar phenomena with higher spectral, space and time resolution. I will discuss some of the recent observations of dynamic activity such as solar flares, Coronal Mass Ejections, prominence eruptions, outflows and jets. Most of the indicators of magnetic activity owe their existence to the emergence of new magnetic fields from the solar interior. This emergence occurs on scales from granulation to full blown active regions. Recent simulations are highlighting the important physical processes responsible, from convection driven emergence to magnetic buoyancy emergence. Finally, the interesting problem of why the solar corona is so hot will be discussed. Ideas for coronal heating will be mentioned and some recent simulations presented. What is clear is that magnetic complexity very quickly develops from relatively simple magnetic structures.
