In this review talk I cover some recent developments in understanding the role that magnetic fields play in cataclysmic variables. I discuss the recent DNO QPO unification models; the disk-magnetosphere boundary; some issues concerning the soft blackbody component and the nature of the X-ray spectra in MCVs; whether the SW Sex stars are magnetic, and finally I mention the weird behavior of FS Aur and HS 2331+3905.

Resumen

Resumen

En este resumen se cubren algunos aspectos de los recientes desarrollos en la comprensión del papel que juogan los campos magnéticos en variables cataclísmicas: presento una discusión sobre los recientes modelos do unificación DNO QPO; los límites de la magnetosfera del disco; algunas cuestiones relacionadas con la componente suave de cuerpo negro y la naturaleza de los espectros de rayos X en MCVs; si las estellas SW Sex son magnéticas; y finalniente, menciono el raro comportamiento de FS Aur y HS 2331+3905.
