When elemental abundances are normalized to their values in the solar photosphere, it is found that elements with low values of the First Ionization Potential (FIP) are enhanced in abundance in the solar corona relative to elements with high values of the FIP. In order to account for this so-called "FIP effect", we suggest that the corona is supplied with material from localized sites where magnetic flux tubes of opposite polarity come into contact. When this process of opposite-flux-tube-interaction (OFTI) occurs in a partially ionized medium, it provides a natural method for enhancing low-FIP elements in the corona. Numerical modelling of OFTI using a two-fluid code has been reported by Arge and Mullan (1998): the enhancement of low-FIP elements depends on the ratio of two time-scales, one for ions the other for atoms. The model contains the important feature that, because of a particular feature of the chromosphere in solar-like stars, there is a built-in regulatory mechanism of the enhancement of the low-FIP elements. This is especially important in the context of recent discoveries of FIP bias in stars other than the Sun.
