We designed and fabricated cylindrical magnetic ac markers for magnetic motion capture system. The ac marker is 12 mm long and 7 mm in diameter. The inductance of the coil was calculated using Dwight's formula. A magnetic field of 2.4×10^<-7> Oe was measured using a high-frequency carrier type thin-film magnetic field sensor combined with a carrier-suppressing circuit. The distance detected between sensors and marker was 1250 mm.
