Abstract:

The magnetic flux sensor MFS is a newly discovered device for measuring resistance and permeability of metal samples. A preliminary investigation of its sensitivity showed it to be capable of determining the resistance of metal samples to within 1.1 x 10 to the -7th power. This report contains the results of a theoretical investigation starting with a development of AC magnetic circuit theory. Use of theory substantially reduced the difficulties in nulling the sensor and was also important together with an additional measurement in showing why the ultimate sensitivity was not achieved. Determination of the distribution of the magnetic field in the sensor gap was made experimentally and is reported here both to demonstrate use of the sensor and to determine where radiation would produce a maximum response should the sensor be used as a radiation detector. Finally, some work related to the determination of the emissivities of foils is presented. Author
