Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

法拉第定律指导体环路里的磁通量发生变化时，在导体环路上产生电动势，而且服从围线积分律；麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时，在以太空间的该点产生电场，即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论，而且服从微分律；洛伦兹磁力指金属电子切割磁力线时，金属电子受力沿着导体漂移而形成感应电流，其实，无论线圈运动或是磁铁运动，只要磁场与导体存在相对运动，则金属电子必然切割磁力线，即，"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的，都属于金属电子切割了磁力线。

The choice for material of iron core, all the structure design and the method of collimation for the magnet were also described. Simulation results of Opera show that when the length of the core is 220 mm, the effective magnetic length is about 302 mm and the maximal magnetic density is around 0.215 T at four interior angles. Corresponding field uniformity is within 0.8% in the area of 133 mm×200 mm.

根据磁铁的设计指标，给出了磁铁设计要求铁芯材料选择方法、整体的结构设计以及如何对磁铁进行定位和准直，并采用Opera程序进行模拟计算，结果表明：当铁芯长度为220 mm时，磁有效长度大约为302 mm；磁感应密度最大的地方在4个内角上，约为0.215 T；在133 mm×200 mm的平面范围内，磁场均匀性优于±0.8%。
