MHD effect using micropolar fluid between rough conical bearings is analyzed in this paper. The Reynolds equation is derived in the form of magnetic field using the Eringen principle with Christensen theory. The stochastic modified Reynolds equation for two types of one-dimensional structure, the radial roughness pattern and azimuthal roughness patterns is derived for micropolar fluid. In terms of dimensionless pressure, load carrying capacity and time, the numerical results are presented. The importance of roughness, MHD and micropolar fluid is greater than that of the classical Newtonian case. From the analysis, the impact of micropolar fluid and electrically conducting fluid increases the load carrying capacity further decreases the time relative to the Newtonian instance. On the whole, the squeezing film characteristics of conical bearings is improved for higher values of coupling number and Hartmann number.
