Fiber scanner has been developed for the precise medical endoscope which often makes a high quality inspection in the narrow room of human bodies such as stomach organ.so high-resolution, small size endoscope has been required. In this paper, we use the two-spring-constant electromagnetic-driven fiber scanner which consists of an optic fiber, a collimator lens, a permanent magnet and tilted coils for experimental study. The internal magnetic field strength of coil depends on the winding number of the coil, coil radius and current. The magnetic force and fiber displacement measurements were performed for different winding number, coil radius, angle between magnet and coil, voltage to compare their best performance. It is proven that 300winding number 4.99voltage, 1.5mmcoil, 30degree angle have the largest fiber displacement 4.3mm and magnetic force 0.0017N.We obtain 245.23Hz high frequency with magnetic force 0.0017N by Coventor software simulation.
