A method for determining the local magnetic induction near the cut edge of the ferromagnetic strip

• The proposed algorithm increases the accuracy of the needle probe method.
• Distribution of magnetic induction in the area close to the cut edge is tested.
• The author examines the proposed new algorithm for the needle probe method.
• Significant reduction of the error is achieved by use of the new algorithm.

The paper deals with the problem of precise determination of the local magnetic induction. The author proposes a new way of doing the measurements using the classical needle probe method. The proceeding algorithm combined with the proposed approximation of the ΔU voltage drop, contributes to a significant increase in the accuracy of the determination of the magnetic induction distribution in the zone near the cut edge.
