Results show that, conventional pointdipole model has overrated the magnetic-induced shear modulus of the magnetorheological elastomers.
计算结果表明,传统的点偶极子模型高估了磁流变弹性体的磁致剪切模量;

But if the goal is to reproduce sounds accurately, then a speaker must be either an acoustic point source (monopole, omni-directional) or an acoustically small bi-directional source (dipole).
This article gives a description of a method to ascertain the magnetic field at any arbitrary point of magnetic dipole space by a kind of reciprocity principle.
