“…The above 4 vector features are extracted to depict the force ellipse, and the mathematical derivations or numerical calculations are introduced in detail in Appendix in [20]. For rotating HMF, the tangential component and its moment produced by the force ellipse are very crucial, so 6 vector features are supplemented.…”

The induced electromagnetic field (iEMf) and the time-varying Lorentz force field (tvLFf) generated by a 4-pole magnetic field are studied in a 2D model, simplified from a round billet continuous casting model. The results are as follows: ①Both the 90° spatial rotational symmetry of the 2D geometric model, and the 90° phase (or time) rotational symmetry from the 2-phase exciting currents collectively determine the fundamental features of the iEMf and tvLFf in the ROI; ②The force ellipses in most of the ROI have the same rotational direction as the rotating magnetic field; ③The region near the connecting lines of the magnetic pole pairs typically contributes more to the tangential force and time-mean component of the force ellipse; ④The effects of the mold on the iEMf and tvLFf are uiquitous: it weakens the Strength and alters the Morphology features and Tide features.
