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.
