THE HARVEY AND HARVEY MODEL (1973)
The model by Harvey and Harvey (1973) suggests that magnetic flux is
removed from the sunspot at the photospheric level. This produces pairs
of MMFs in which magnetic elements of opposite polarity to the sunspot
tend to be formed farther out. Mayer (1974) and Ryutova et al.
(1998) showed some evidence that the inner footpoint of the MMF bipoles
shares the sunspot's polarity, which supports the model of Harvey and
Harvey (1973).
