Qualitative analysis of a mutual induction linear transducer and that of angular displacement transducer are more difficult than is generally supposed, and few reports have been published. As a mutual induction linear transducer or an angular displacement one constitutes an open magnetic circuit with a cylindrical rod or a circular shaped core , it is not easy to keep magnetic quantities, for instance flux density, constant along the core, because demagnetizing force exists. In this paper, in order to clarify the conversion characteristics and to obtain the fundamental design data of the transducer, the theoretical equation of the output voltage has been obtained by a flux distribution method, taking into account the demagnetizing force. The fundamental expressions of the output voltage, the voltage and current sensitivities, and the range of linearity are generalized by using the flux distribution along the core, and one can find the relationship between the core dimensions and the winding construction of the transducer. The conversion theory which utilizes flux distribution method will not only be applied to the design of a differential transformer, but also to the analysis of other open magnetic circuitry, such as an electromagnet and a magnetic thin film.
