Abstract: The magnetic field distribution in and around thin ferromagnetic
structures has been explored. Extrapolation and mathematical air flux
compensation were used to obtain magnetic quantities on the sample surface and
inside the sample, minimizing systematic errors for flux-metric and
Gauss-metric measurements. A magneto elastic model was applied describing large
deformations of thin ferromagnetic structures in a static magnetic field. The
model based on global balance equations obeys the conservation of energy and
momentum. Exemplified by the deformation of a soft-magnetic elastic plate in a
uniform transverse magnetic field, the numerical evaluation of the model was
compared to experimental results. Field distribution and deformation of the
plate in a stepwise increased external field showed good agreement from small
magnetization up to saturation.
