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.

A sensor system comprising an axially symmetric vertical magnetic field component exciting sensor system comprising:
- an axially symmetrical magnetic substance comprising a circular, oval or polygonal shaped flat disk and a protrusion capable of forming magnetic path for exciting vertical magnetic field components, formed on a center of the flat disk, wherein:
- said sensor system is used for a response system having an IC connected to and wound by a coil which generates signals, wherein
- said sensor system is directly mounted on a metal surface or buried in a hollow formed on the metal surface, and wherein
- the hollow is formed along a central axis of the flat disk.
A sensor system comprising an axially symmetric vertical magnetic field component exciting sensor system comprising:
- an axially symmetrical magnetic substance comprising a circular or polygonal shaped flat disk on which a flatly wound coil is mounted, wherein the coil is mounted only on the disk, and a protrusion capable of forming magnetic path for exciting vertical magnetic field components, formed on a center of the flat disk.
