Abstract

The paper deals with the evaluation of magnetic fields in a system of a relatively long-conductive ferromagnetic-strip with nonlinear characteristic. The field is produced by an a.c. excited relatively short coil wound around the strip. The investigated system is similar to a magnetic field sensor system (described recently) which employs nonlinear eddy current effects in the sensing process. The analysis in the paper depends on linearization of the magnetic vector-potential equations by assuming that all field components are sinusoidal everywhere, and by imposing an appropriate change of 11 with the material depth. The linearization process enables the integration of the field equations by Fourier transform. The evaluated results compare favorably to experimental results.
