An analysi. has been performed to study the problem of magneto-hydrodynami. （MHD） squeeze flow of an electri.ally conducti.g flui. between two i.fi.i.e, parallel di.ks. The analyti.al methods called Homotopy Analysi. Method （HAM） and Homotopy Perturbati.n Method （HPM） have been used to solve nonli.ear di.ferenti.l equati.ns. i. has been attempted to show the capabi.i.i.s and wi.e-range appli.ati.ns of the proposed methods i. compari.on wi.h a type of numeri.al analysi. as Boundary Value Problem （BVP） i. solvi.g thi. problem. Also, the veloci.y fi.lds have been computed and shown graphi.ally for vari.us values of physi.al parameters. The objecti.e of the present work i. to i.vesti.ate the effect of squeeze Reynolds number, Hartmann number and the sucti.n/i.jecti.n parameter on the veloci.y fi.ld. Furthermore, the results reveal that HAM and HPM are very effecti.e and conveni.nt.
