摘　　要：计算了单匝通电线圈、亥姆霍兹线圈和有限长通电螺线管对同轴通电细圆环的作用力。选取适当的电流、距离或单位长度的匝数，细圆环受到的作用力可从10^-1～10^2N变化，利用它可以研究压电陶瓷和压电晶体的特性。In this paper, we calculate the force of thin circle with current in the magnetic field of the single loop, the Helmholtz coils and the finite solenoid, which are coaxial with the thin circle. Choosing the current, the distance and the dense loop in unit length properly, we can get a wide interval of the force, such as 10^-1～10^2N, which is useful to study the characteristics of piezoceramics and piezocrystals.
