This paper presents magnetic properties of permanent magnet wires developed for applications of micro magnetic actuators. Nd-Fe-B and Sm-Co permanent magnets have been contributed to improve efficiency of electrical machines and magnetic actuators and to miniaturize their size and weight. Recently use of Nd-Fe-B based permanent magnets in micro machines is also paid attention to improve moving performance such as increasing torque and reducing energy losses. Our target is producing a 0.2mm diameter wire-shaped permanent magnet directly by using a spinning method in rotating liquid for a medical application. In this paper, the magnetic properties of Nd-Fe-B and Sm-Co based permanent magnet wires developed with different nozzle orifice size (0.1 mm, 0.2 mm and 0.3 mm in diameter) are discussed. The result shows that the coercive force of the wire samples made by using the nozzle whose orifice sizes is 0.1 mm was improved
