And obtained the law of the magnetic force changed with the structure of the Helmholtz coils, densities of the samples and Ampere-turns et al. 得出了电磁力随线圈结构、安匝数和试件密度的变化规律。
Putting the cylindrical sample in the field, and numerical simulate with ansys FEM, we have studied the electromagnetic force which the sample beared in different Helmholtz coil for different densities samples, different Ampere-turns et al by controlling variable in the established experimental model. 通过对所构建的实验模型采用控制变量法,研究了不同结构的亥姆霍兹线圈、不同试件密度、不同线圈安匝数等条件下试件所受的电磁力的情况。
The influence of Ampere-turns and distance the roll rim enters the yoke on the height of liquid tin contained by the electromagnetic field have been investigated experimentally with an apparatus built by ourselves. 研究了感应圈安匝数及辊端进入磁轭的深度对侧封液态金属高度的影响规律。
Measuring V-A Characteristic of Current Transformer with High Ampere-turns Using Low-frequency Generator 用低频电源测量高安匝数电流互感器的伏安特性
