Abstract:

We present a method for the estimation of the DC B-H curve of a straight magnetic wire which is used as a core for fluxgate sensor. An inverse technique is used as the direct precise measurement is practically impossible. 2D time stepping and 3D time harmonic finite element methods are used for numerical calculations to find a proper magnetization curve from the measurements of induced voltage into the pickup coils. Combined rational and power functions are utilized to model the magnetization curve, which is later used for numerical analysis too.
