Description
We show that the magnetic DC white dwarfs cannot have evolved from stars of spectral type DA. A separate origin is necessary, and a direct evolutionary connection between the magnetic DC stars and the nuclei of planetary nebulae seems plausible. Such a connection implies photospheric field strengths 10 -10 gauss in planetary nuclei, which may be large enough to be detectable. In addition, we find that magnetic white dwarfs must be hotter than some (weakly massdependent) limiting effective temperature. This prediction is potentially susceptible to observational verification. Subject headings: magnetic stars - stellar evolution - white dwarf stars
