Internal heat generation plays a very cogent role in the field of engineering and technology. Applications of Internal Heat generation can be seen in joule heating due to the flow of an electric current through a conducting fluid, the radiative heating and cooling of molten glass and heating of water in a solar collector and also in processing of molten glass. Material itself can produce heat by the source available in it, hence by this the convective flow of fluid takes place within the layer through local heat generation, in particular which can observed in  Combustion and fire studies, geophysics, reactor safety analysis and metal waste form development for  nuclear fuel. Because of this internal heat, the thermal energy is transformed towards the surface of the earth  and also in  multi component fluids it helps in convective flow.\    There are only few studies are available to  examine the facts on  the effect of internal heating on convective flow in a fluid layer. Shivakumara and  Suma studied the effect of  flow and internal heat generation on the onset of convection using rigid and perfectly conducting boundaries. Mokhtar studied the uniform distribution of internal heat generation in an Eringen’s micropolar fluids with feedback control. Radha B.N investigated with magnetic field and electrically conducting micropolar fluid. Vasudha Yesaki did analysis on effects of  ITBT with internal heat  between two horizontal surfaces in a micropolar fluid. R.K Vanishree investigated effects of flow with internal heat in anisotropic porous medium using Rayleigh-Ritz technique. Sanjok Lama investigated  Rayleigh-Bénard- convection in electrically conducting micropolar fluid and internal heat with magnetic field  using Galrkin technique.\    Classical fourier law is an well known consequence of heat propogation with an infinite velocity due to parabolic in nature. To explore heat transfer characteristics with variable thermal conductivity Maxwell introduced the Maxwell cattaneo law instead of classical fourier law,  i.e egin{equation*}  au dfrac{dvec{Q}}{dt}+vec{Q}=-chi
abla T end{equation*} Where Q is the heat flux, t is a relaxation time and x is the heat conductivity.\ The difference between the classical fourier law and Maxwell cattaneo law is in the cosideration of  speed.  In the above equation heat propogation takes place with finite speed due to hyperbolic in nature. It is due to heat conductivity  and the conservation of energy equation which describes heat propagation with finite speed.  The effects of result from the substitution of the classical Fourier law by the non-classical Maxwell-Cattaneo law on the Rayleigh-Bénard Magneto-convection in an electrically conducting micropolar fluid is investigated by Maxwell, Cattaneo, Lindsay and Straughan, Siddeshwar, S.Pranesh, Puri and Jordan, S.Pranesh and Rojipur Kiran,  Maruthamanikandan and  Smita S. Nagouda, S.Pranesh and Smita S. Nagouda, F. Ekoue extit{et al.}, C.I. Christov.\ Micropolar fluids are fluids with microstructure. These fluids can support stress moments and body moments and are influenced by the spin inertia.Eringen introduced the theory of micropolar fluids. Rayleigh Benard convection in Eringen’s micropolar fluid have been investigated and concluded that the stationary convection is the preferred mode by A.C.Eringen, Datta and V.U.K sastry, S.Pranesh, P.G. Siddeshwar and S.Pranesh.\  The main aim of this paper to study the effect of internal heat generation on a Rayleigh-Benard Magneto convection in a micropolar fluid with Maxwell-cattaneo law.
