A　new　mathematical　model　for　a　flexible　blade　coater　is　proposed　and　analysed　for　slip　and　magnetohydrodynamic　(MHD)　effects　in　blade　coating　process.　The　slip　is　considered　at　the　blade　surface　and　magnetic　field　is　imposed　normal　to　the　flow.　To　obtain　the　velocity　profile,　pressure,　pressure　gradient,　volumetric　flow　rate　and　maximum　pressure　both　exact　and　numerical　solutions　are　utilized.　In　order　to　obtain　the　numerical　solution　shooting　technique　is　applied.　The　interesting　physical　quantities　like　load　and　deflection　are　calculated　and　presented　in　graphical　and　tabulated　form.　The　influence　of　the　Hartman　number　the　slip　parameter　and　normalized　coating　thickness　parameter　on　the　flow　and　deflection　are　discussed　graphically.　In　the　presence　of　magnetic　field　and　slip　the　fluid　velocity　and　hence　blade　deflection　can　be　controlled.
