This paper discusses some features in Planetary Nebulae and Protoplanetary Nebulae that are addressed by several works on MHD. We review different scenarios for the origin of magnetized winds, either for Protoplanetary Nebulae or Planetary Nebulae, and discusses the production of axisymmetric flows, the confinement of flows and the production of jets and ansae, point-symmetric nebulae and the periodic shells around Planetary Nebulae and Protoplanetary Nebulae. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR] |
