Abstract
The device for measuring magnetic field by using a magnetoresistive sensor comprises at least one magnetoresistive sensor (), a module () for measuring the resistance of the magnetoresistive sensor (), a generator module () for generating an additional magnetic field in the space containing the magnetoresistive sensor (), and a control unit () firstly for selectively controlling the generator module () to apply an additional magnetic field pulse possessing a first value with first polarity that is positive or negative and magnitude that is sufficient to saturate the magnetoresistive sensor (), and secondly for selectively controlling measurement of the resistance of the magnetoresistive sensor () by the module () for measuring resistance.
