magnetic cataclysmic binary A cataclysmic binary in which the white dwarf primary has a strong magnetic field that radically affects the accretion flow in the system. Magnetic cataclysmic binaries (also known as magnetic cataclysmic variables) fall into two main classes based on the strength of their magnetic fields: AM Herculis stars (or polars) and DQ Herculis stars (or intermediate polars).
