Stray field due to eddy currents on a cylinder with azimuthal cuts: A comparative analysis of the cut shape effect

The paper deals with the design of azimuthal cuts on a conducting cylinder. It analyses the effect of various cut shapes in minimising the stray magnetic field in the cut region, when an orthogonal magnetic field is penetrating through the cylinder. Both an analytical model and a finite element code are used for the analyses in the time and frequency domain. Results from both methods are compared and a fairly good agreement is found. The non‐linearly tapered cut results as the best solution for minimising the stray field.
