Summary: | Using the two fluid model, the problem of two-dimensional steady-state magnetic reconnection in incompressible resistive weakly ionized plasmas is analysed. Under the strong-coupling condition such as in the Sun's photosphere, it allows us to express the current sheet analytically. In this case the current sheet scales as phi 1/2. Then this model is used to understand magnetic flux cancellation which is observed in the Sun's magnetograms. To account for a cancelling flux of 1X1018 Max in a time interval of 77 min, the width of the current sheet is about ten kilometres. |
