Abstract :
Two methods of magnetic and dielectric flux mapping by means of experimental models are described in this paper. Both methods use resistance models, through which current is passed; electrical conductivities of model parts are adjusted to correspond to magnetic or dielectric permeabilities of corresponding parts of the original design, and paths of electric current flow and electric equipotential lines in the model correspond to magnetic or dielectric flux lines and equipotential lines in the original design. Low melting point waxes with carbon or graphite inclusions are particularly suitable for model making purposes due to easy working properties and ready control of the electrical conductivity.
