研究了线圈间距、匝数、个数以及不锈钢套筒对脉冲磁体产生磁场的影响规律。在储能电容和电压不变的前提下，研究结果表明：增加线圈间距会导致磁感应强度降低，磁力线包络增大，但总电流达到峰值时刻减小；增加线圈匝数，峰值电流明显减小，会降低磁感应强度，但有利于抑制磁力线包络；增加并联线圈个数，有利于产生较长的均匀区，但是在供能一定的条件下，磁场强度有所降低，同时总电流达到峰值时刻减小。总体来看，在一定均匀区长度的设计要求下，减少单个线圈匝数，增加并联线圈个数，能够得到磁感应强度更大、均匀性更好的磁场，但要考虑线圈承载电流的能力。另外，不对称的阴阳极金属结构会导致磁场不对称分布，且磁感应强度达到峰值时刻要晚于总电流达到峰值的时刻。

The effect of structural parameters of solenoid pulsed magnet on magnetic field is studied, including the number of turns, the number of coils, the distance between multi-coils and stainless steel cylinder. Under the condition that the capacitor storing energy and the voltage which supplies power are both constant, the amplitude of magnetic flux density is reduced and the fluctuation of magnetic field lines is increased contrarily when increasing the distance between multi-coils, but the total current reaches its peak earlier. Increasing the number of turns in each coil can obviously reduce the peak of total current and thus the amplitude of magnetic flux density. However, it is beneficial for reducing the fluctuation of magnetic field lines. With the increasing of coils number, the length of uniform magnetic field region becomes longer, the amplitude of magnetic flux density is reduced with constant supplied energy, and the total current reaches its peak earlier. On the whole, when the length of uniform magnetic field region is constant, decreasing the number of turns and increasing the number of coils are both effective ways to obtain a stronger magnetic flux density and better uniformity. But it is limited by the capacity of the coils to carry current. In addition, the stainless steel cylinder causes the distribution of magnetic field to be asymmetrical, and the amplitude of magnetic flux density reaches its peak later than the total current does.
