  Angular Momentum Loss is important for understanding astrophysical phenomena
such as stellar rotation, magnetic activity, close binaries, and cataclysmic
variables. Magnetic breaking is the dominant mechanism in the spin down of
young late-type stars. We have studied angular momentum loss as a function of
stellar magnetic activity. We argue that the complexity of the field and its
latitudinal distribution are crucial for angular momentum loss rates. In this
work we discuss how angular momentum is modulated by magnetic cycles, and how
stellar spin down is not just a simple function of large scale magnetic field
strength.
