This paper presents magnetic flux control to manipulate magnetically-labeled-cells on a chip for regeneration medicine. Proposed device has conical magnetic structures at a gap of magnetic loop in order to focus leakage fluxes while previous works employed open loop magnetic structures . A cellular chip is inserted into a gap of magnetic loop. Up-and-down motion of a conical magnetic structure regulates magnetic strength on a chip. A pneumatic microactuator for large up-and-down motion is integrated with conical magnetic structure. Successful results of focusing and switching of magnetic flux by proposed device is reported in this paper.
