Abstract :
The development of a 3-dimensional (3-D) navigation system of ferromagnetic particles in a flow system was performed. In order to improve the practice of using externally-applied magnetic fields for targeting the magnetic particles to a circumscribed body region, we tested the feasibility of a novel 3-D navigation system, made by applying a strong external (magnetic) field through a GdBaCuO bulk superconductor. A 3-D theoretical model is proposed and used in order to evaluate the efficiency of the navigation/retention of magnetic particles in the flow system. Furthermore, an experimental model system was made and the efficiency of a prototype system was examined. Comparisons of experimental and the corresponding calculation results were made to examine the theoretical model system
