Abstract
The present invention provides an axially symmetric vertical magnetic field component sensor system capable of intensifying vertical magnetic field components. The sensor system comprises an axially symmetrical magnetic substance comprising a circular, oval or polygonal shaped flat disk and a protrusion formed on a center of the flat disk. The sensor system is used for a response system having an IC wound by a coil which generates signals and the sensor system is mounted on a metal surface or buried in a hollow formed on the metal surface.
