Abstract

PURPOSE: To simplify the distribution of the uniformed conductors by supplying the current featuring a certain correlation to each uniformed conductor via the electric circuit to secure the offset and compound for the harmonic function near the test sample.
CONSTITUTION: The energizing circuit, which generates the magnetic field slope of the enen-order of Y to the uniformed conductor, consists of n units of potentiometer 1 which generates the output voltage of E0WE2n-2, amplifier 2 which uses each element of the matrix (αij) as the gain plus addition amplifier 3. As a result, current I1 features as I1=α11E0+α12E2...+α1nE2n-2=I11+I12+...+I1n. After this, I2WIn can be obtained in the same way. As a result, the Y0 component and Y2 component can be varied independently by varying current E0 and E2 respectively. In the practical use, the generation of the magnetic field slopes of Y2 and Y4 is enough, and thus the distribution of only two sets of uniformed conductors is required.
