The paper describes a system for measuring of magnetic induction on the wind generating unit. The manner of operation and the application of the Hall effect probe are detailed. Dynamic electromagnetic field computing results are shown through application of MKE on the synchronous generator model installed in a windmill unit and compared to the actual metering results. Two subsequent magnetic field calculations on the modified model were made to be used for analyses of the obtained results. Influences of air gap forms and saturation to time dependence of magnetic induction at a point within the machine are explained.
