【摘要】 本文提出用间接边界元法计算任意界面的永久磁铁所产生的空间磁场，推导出其磁场计算公式。实际计算了稀土永久磁铁的磁场分布，并与实测值进行了比较。实际计算结果表明这是一种简单而实用的方法。更多还原

【Abstract】 In this paper, an IBEM(Indirect Boundary Element Method) is presented for calculating permanent magnet field, and the formula of calculating magnetic field intensity is deduced. By calculating and measuring two real engineering examples, it is proven that the IBEM is simple and useful.更多还原
