FLUX GATE MAGNETOMETER INCLUDING BACKING PLATE |
摘要 |
A magnetometer having a flux sensing head including a core and a magnetically permeable backing plate opposite the core with second harmonic driven detection coils on the core for sensing a static magnetic field extending between the core and the backing plate. The magnetometer is designed for detecting the presence of magnetic inks between the detection head and the backing plate.
