  Magnetic activity in M-dwarfs present enigmatic questions: On the one hand
they have higher field strengths and larger filling factors than the magnetic
field on the Sun, on the other hand, they are fully convective and their
atmospheres are more neutral, hence they do not have an undershoot layer for
magnetic flux storage and as we show here, cannot have small-scale dynamo
action in their photospheres either. We present a discussion of these facts and
propose a new numerical model to investigate M-dwarf magnetism.
