An alternative coil system to the Helmoholtz coil-pair is described for the stimulation of biological tissue and cells: a relatively large box coil made of copper or aluminum sheet stock. The design is based on the principal determinant of the induced electric field, namely, the magnetic vector potential (A), in the equation, [formula: see text]. The second term in the equation is needed when boundaries of the conducting medium are in close proximity to the region of interest, such as in a culture dish. An electric surface charge builds up on the boundaries to generate an electric field which cancels [formula: see text] at the surface. The effectiveness of the new coil is demonstrated in a study of the outgrowth enhancement of axons from rat embryonic dorsal root ganglia.
一种由铜或铝板制成的相对较大的盒式线圈。该设计基于感应电场的主要决定因素，即磁矢势（A），在方程[公式：见原文]中。当导电介质的边界靠近感兴趣区域时，例如在培养皿中，方程中的第二项是必需的。电表面电荷在边界上积累以产生一个电场，该电场在表面抵消[公式：见原文]。在一项关于大鼠胚胎背根神经节轴突生长增强的研究中证明了新线圈的有效性。
