Coating　is　a　process　that　improves　and　enhances　life,　quality　and　efficiency　of　the　web.　Common　industrial　adhesive　application　to　board　and　paper,　metal　foils　polymer　coatings,　photographic　film　emulsions,　recording　films,　textile　fabrics,　paints,　coating　on　food　items,　medicine,　catalogues　are　common　examples.　There　are　many　fluids　that　are　used　as　coatings.　This　paper　analyses　blade　coating　using　both　plane　as　well　as　exponential　geometries　along　with　slip　and　magnetohydrodynamics　effects　for　a　Carreau　fluid　model.　To　study　the　blade　coating　phenomenon,　slip　is　introduced　at　the　blade　surface　and　a　magnetic　field　is　applied　normal　to　the　fluid　flow.　The　LAT　(Lubrication　approximation　theory)　has　been　introduced　to　convert　governing　partial　differential　equations　into　a　simpler　form　and　a　numerical　solution　is　obtained　by　using　shooting　method.　The　significant　physical　quantities　like　volumetric　flow　rate,　pressure,　velocity,　load,　coated　film　thickness　and　pressure　gradient　are　discussed　in　detail.　The　effects　of　power　law　index,　slip　parameter,　Weissenberg　number　and　Hartmann　number　on　these　physical　quantities　are　presented.　The　observations　are　depicted　in　tabular　data　and　in　the　graphical　form　as　well.　The　Weissenberg　number　and　Hartmann　number　play　a　very　important　role　in　controlling　the　load　and　coated　film　thickness.
