Abstract :
The study concerns a flat large construction steel plate of varying thickness magnetized with a C-core magnet. Modeling of the time- and spacefield distribution inside the plate is carried out. The novelty of the approach consists in carrying out a transient solution when a driving saw-tooth voltage is used. Also new is a refined magnetoacoustic emission (MAE) signal modeling, numerically deduced for various frequencies, and compared with experimental data. The distributions of fields are indirectly compared with stray field measurements and a close agreement is found
