Analytical calculations of pressure and velocity components in human hip joint for synovial unsymmetrical fluid flow are presented in this paper. Following assumptions are taking into account: unsteady, isothermal and incompressible synovial unsymmetrical non Newtonian synovial fluid flow, rotational motion of bone head, variable magnetic field and constant synovial fluid density. The method of solutions of hydrodynamic lubrication problem in human hip joint in presence of unsteady magnetic field is presented in this paper.
