The distribution of electromagnetic fields of linear electromagnetic stirrer were simulated by ANSYS?5 6 software. Through the contrast between the calculation results and the measured results, the reliability of the calculation was validated. On the condition of unchanged structure of the stirrer, the electromagnetic fields distribution of one pole pairs and two pole pairs and their relation with the currents used were analyzed. The magnetic induction of one pole pairs and two pole pairs change linearly with the currents used with the unchanged structure of the stirrer, while the magnetic induction of the former are larger than that of the latter at the same currents.
