©　2017　Pushpa　Publishing　House,　Allahabad,　India.　The　paper　investigates　the　revolving　ferrofluid　in　a　disk　by　considering　the　magnetic　field-dependent　viscosity.　The　boundary　layer　equation　is　obtained　using　Neuringer-Rosenweig　model.　The　governing　equations　of　the　problem　are　as　a　system　of　nonlinear　ordinary　differential　equations　with　the　boundary　conditions　at　infinity.　These　equations　are　solved　using　the　Runge-Kutta-Fehlberg　procedure.　This　method　uses　a　shooting　technique　to　transform　the　boundary　value　problems　to　an　equal　initial　value　problem.　In　the　results　of　this　paper,　the　supposed　value　of　infinity　is　examined　and　the　results　are　reported　for　different　values　of　it.　The　transformed　parameters　for　axial　and　radial　velocities　are　presented　for　some　cases.
