Abstract: The theory of collisional cross field diffusion and transport of a fully ionised singly charged plasma particles is analysed theoretically at the onset of an induced anisotropy (T╻╻≠T⊥) in plasma temperatures where T╻╻ and T⊥ represent the components of temperature along the magnetic field direction and the direction perpendicular to it, respectively. The modified diffusion transport coefficients like the electrical resisitivity (η˔) and thermal conductivity (K) are found to decrease significantly with increase in the thermal ratio (T╻╻/T⊥) while both the E⃗ X B⃗ drift velocity and the thermoelectric coefficient (λ) remain independent of the thermal anisotropy. However, in the limiting approximation (T╻╻=T⊥), the results agree with the early isotropic works of Rosenbluth and Kaufmann, Phys Rev, 1 (1958) 109, Goldstone and Rutherford [IOP Publishing 1995, Braginskil (1965)].
