在太阳黑子中,在产生地球磁场的发电机中,以及在用于各种受控实验的实验室等离子体中,都可以发现流动在磁性介质中的电流。最近,参与该项目的研究人员确定了磁螺旋度(这是一个拓扑学概念)可以量化磁场的扭曲或多节,并统一了一些观测结果。本研究是对这一概念的实验研究,利用实验设备进行实验室等离子体实验。
英文摘要
Currents flowing in magnetic mediums are found in sunspots, in the dynamo generating the Earth's magnetic field, as well as in the laboratory plasmas used in a variety of controlled experiments. Recently, researchers participating in this project have determined that magnetic helicity (which is a topological concept) could quantify the twistedness or knottedness of magnetic fields and unify a number of observations. The research is an experimental investigation of this concept using experimental equipment to carry on laboratory plasma experiments.
