中文摘要：

在现在的工作，在为扔 multicrystalline 硅设计了的方形的冷坩锅的电磁的地的力量和分发被使用一个小卷方法测量并且分析。结果证明在垂直方向，磁性的流动密度(B) 的最大值在卷的中间上面稍微在位置出现，然后 B 向双方稀释，并且更减少到坩锅的底部。在水平方向，从边(角落) 到中心， B 第一逐渐地，然后稍微减少中心的增加。当时沿着坩锅的内部方面，分发是相对一致的，特别在有效代理范围。B 与增加输入力量增加。移动卷到坩锅， B 增加和电磁的地的有效代理范围的顶变得更大。为有不同弦音器的卷，五拐弯卷能导致最高磁性的流动密度。

英文摘要：

In the present work, the strength and distribution of electromagnetic field in the square cold crucible that designed for casting multicrystalline silicon were measured and analyzed by using a small coil method. The results show that in the perpendicular direction the maximum of magnetic flux density （B） appears at the position slightly above the middle of the coil, and then B attenuates toward both sides, and decreases more to the bottom of the crucible. In the horizontal direction, from the edge （comer） to the center, B firstly decreases gradually, and then slightly increases in the center. While along the inner sides of the crucible, the distribution is relatively uniform, especially in the effective acting range. B increases with the increasing of the input power. Moving the coil to the top of the crucible, B increases and the effective acting range of the electromagnetic field becomes bigger. For the coils with different turns, the five turns coil can induce the highest magnetic flux density.
