已针对 DIII-D 等离子体确定了测量电流分布的无感部分。用于确定量 E·B 的通量表面平均值的技术和电阻率模型将电流分布分为感性部分和非感性部分。分析直接表明，新古典电阻率足以解释实验观察结果，而斯皮策电阻率则不然，并且等离子体中存在大的非感应电流，预计会有大的中性束电流驱动和压力驱动自举电流。
The noninductive part of the measured current profile has been determined for DIII-D plasmas. A technique for determining the flux surface average of the quantity E· B and a model for the resistivity separates the current profile into inductive and noninductive portions. Analysis shows directly that neoclassical resistivity is adequate to explain the experimental observations, while Spitzer resistivity is not, and that a large noninductive current exists in plasmas for which large neutral beam current drive and pressure driven bootstrap currents are expected.
