This paper purposes a numerical model of drug targeting using wedge-like magnetic device. The magnetic liquids play a crucial role as drug carriers in the human body. The wedgelike magnetic is also utilized to focus magnetic liquids. The Finite Element Method, FEM, is applied to solve two important sets of partial differential equation. Electromagnetic field is described by Maxwell equation and velocity field is expressed by Navier-Stoke equation. The resultshows the potential to target drug in the tumor cell locally.

The magnetic liquids such as ferrofluids, biocompatible magnetic nanocarrier, play an important role as drug carriers in the human body. Based on Maxwell's equation and Navier-Stokes equations, a time-dependent analysis of a twodimensional computational model of magnetic fluid flow is purposed. The FEM is applied to solve Maxwell's equation for a static magnetic field and Navier-Stokes equations for fluid dynamics. The result of magnetic field has some influences to ferrofluid dynamic flow in blood vessel.
