　　其特殊磁極適合于不同直徑的盤(pán)圓，電磁鐵的選擇取決于盤(pán)圓的長(zhǎng)度，如電磁鐵足夠長(zhǎng)，則一次可沿長(zhǎng)度方向吊運(yùn)幾卷盤(pán)圓。
　　
　　The special magnetic pole is suitable for coiled bar with different diameter.The choice of electromagnet depends on the length of coiled bar.If the electromagnet is long enough,it can lift several coils of coiled bar in direction of the length at a time.
