磁岛是磁约束等离子体的一个普遍特征。它们的产生是由于等离子体不稳定性以及外部施加的对称破缺微扰的结果。在核心，已经开发了有效的抑制技术。然而，即使是薄岛，也可以观察到对旋转和海流剖面的非局部影响。这激发了人们利用磁岛控制等离子体传输的兴趣，特别是在边缘。作为提高我们对微观等离子体动力学的理解的工具，它们也很有趣。
Magnetic islands are a ubiquitous feature of magnetically confined plasmas. They arise as the result of plasma instabilities as well as externally imposed symmetry-breaking perturbations. In the core, effective suppression techniques have been developed. Even thin islands, however, are observed to have nonlocal effects on the profiles of rotation and current. This has stimulated interest in using magnetic islands to control plasma transport, particularly in the edge. They are also of interest as a tool to improve our understanding of microscopic plasma dynamics.
