| 摘 要： | 基于对旋转椭球内部磁场的讨论,采用Matlab数值计算的方法计算了旋转椭球的内部磁场.对于旋转抛物球和双曲球面,用相同方法绕制线圈也能得到均匀的磁场.印证了内部磁场计算的公式,并提出了一种产生大范围均匀磁场的方法.

| Abstract: | Based on discussing for the problem of magnetic field inside an ellipsoidal coil,this paper employs a numerical method to calculate the magnetic field inside several different shapes of coil.Using the same way to wind the coil on ellipsoid,paraboloid or hyperboloid,we find that the magnetic field inside can be uniform.The general formula is also confirmed.Possible ways to generate a large space of uniform magnetic fields are provided. |
