Magnetic Concentrator

Magnetic concentrator (magnetic material) is fabricated on Hall sensor. Magnetic flux passes through the concentrator of a high relative magnetic

permeability selectively. Horizontal component of magnetic flux around the concentrator is bended

vertically. Bended flux flows into the surface of Hall sensor. Thus, Monolithic Hall sensor can detect the horizontal magnetic field [Bz].

Circular disk of magnetic concentrator Symmetrically placed four Hall sensors Arithmetic circuit of measurement data All 3 axes, Bx, By, Bz are measurable!

Magnetic flux inflected by magnetic concentrator is passing through the surface of Hall sensor

X1 = a·Bx + c·Bz X2 = – a·Bx + c·Bz Subtraction: Bx, Addition: Bz
