Abstract
We present the details of an automated flux-type magnetometer that uses numerical integration of the voltage induced in the sensing coils when the sample is moved. The Tchebycheff quadrature method of numerical integration has been used to achieve high accuracy in the integrated output. In relevance to this, we also present design and construction of an electronic circuit (integration limit setting circuit) together with the software for data acquisition using a Z-80 microprocessor. We discuss the advantages and disadvantages of this particular method with reference to others. We also discuss the calibration of this magnetometer.Keywords
