By adopting low-order approximations, a four-dimensional dissipative hyperchaotic system with six control parameters is obtained. Both fluid couple-stress and magnetic parameters delay the onset of convection. In contrast to plain couple-stress convection, the magnetic field instigates the occurrence of Andronov\u2013Hopf, Bogdanov\u2013Takens bifurcations with double-homoclinic connection at the origin near the onset of magnetoconvection when the magnetic diffusivity ratio (the ratio of fluid Prandtl number to magnetic Prandtl number) is less than one. Thereafter the system exhibits periodic attractors near subcritical Hopf bifurcation at nonzero equilibrium points undergoing chaos through period-doubling process. Owing to the interaction between the magnetic field and fluid couple-stress, the present model system exhibits hyperchaos via a suddenly created instability during stable oscillation for critical values of the parameters. <\/jats:p>","DOI":"10.1142\/s0218127418300343","type":"journal-article","created":{"date-parts":[[2018,9,24]],"date-time":"2018-09-24T05:20:28Z","timestamp":1537766428000},"page":"1830034","source":"Crossref","is-referenced-by-count":23,"title":["Bifurcations and Hyperchaos in Magnetoconvection of Non-Newtonian Fluids"],"prefix":"10.1142","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0867-5689","authenticated-orcid":false,"given":"G.
