Overview: Magnetic measurements represent relatively difficult area of the electrical engineering. Classical measurements have been done for the closed specimens but the modern AC measurement should be realized for open steel sheets and strips. The total error of any magnetic measurement depends on the exciting field error, the error of the magnetic to electric variables conversion and the error of integral electric values measurement. The original method of MMF compensation allows measurement of the magnetic properties of single sheets and strips in the same way as the closed specimen properties. The method accuracy is limited due to the finite gain of the feedback loop fulfilling the condition of its stability.
