Document Type and Number:
WIPO Patent Application WO/2010/021032
Kind Code:
A1
Abstract:
A magnetic field sensor comprises a container for containing a dispersion liquid in which magnetic particles are dispersed, a light source for emitting light to the container, and a light intensity measuring means which is disposed on the side of the container opposite to the light source and measures, at need, the intensity of the light transmitted through the container. Consequently, the magnetic field sensor can be made to be a simple structure and can detect a magnetic field with high sensitivity.
