                         crystallization driven dynamo can explain the apparent increase of 
                         magnetism in old metal polluted white dwarfs. We find that the 
                         effective temperature distribution of polluted magnetic white 
                         dwarfs is in agreement with most/all of them having a 
                         crystallizing core, and increased rotational velocities are 
                         expected due to accretion of planetary material that is evidenced 
                         by the metal absorption lines. We conclude that a rotation and 
                         crystallization driven dynamo offers not only an explanation for 
                         the different occurrence rates of strongly magnetic white dwarfs 
                         in close binaries but also for the high incidence of weaker 
                         magnetic fields in old metal polluted white dwarfs.",
