N2  - In this study, the difference(of the classical diffusion tensor (D0, D1,D2 for both steady-state and unsteady-case)for F- region of the ionosphere at the equatorial region is investigated by taking (B=B0z), the geometry of the Earth’smagnetic field and by neglecting the neutral winds velocity (U). Themeasurements were made in the height (280,300,340,390 and 410 km) where the equatorialanomaly was observed predominantly. The magnitudes of the difference ofclassical diffusion tensor for electrons are ∆D0>∆D1 >∆D2for all seasons with respect to both 12.00LT and 24.00LT at F-region.However, ∆D1 and ∆D2 are bigger during nighttime than daytimeand show a behavior reverse to the change with latitude of electron density inthe magnetic equator. It is possible to say that the behavior of them can be theresult of electromagnetic drift and dynamo effect.
