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.
