Problems solved by technology
However, during the use of the coil system, the coil is energized to generate a magnetic field, and the moving charge of the current will generate an electromagnetic force (Lorentz force) in the magnetic field, which will act on the coil, which may cause local deformation of the coil
Once the coil is in use, if it is locally deformed due to the action of electromagnetic force, it will destroy the magnetic field confinement and configuration, thus affecting the confinement of nuclear fusion

Description
technical field [0001] The invention relates to the technical field of magnetic confinement nuclear fusion devices, in particular to a stellarator, in particular to a design method for preventing the three-dimensional modularized coil of the stellarator from being deformed by electromagnetic force during use. Background technique [0002] With the development and progress of society, human beings' demand for energy is increasing, and the world's energy crisis is intensifying. In the existing energy system, traditional non-renewable energy sources such as coal, oil, and natural gas are the main sources. These energy sources not only cause huge pollution to the environment during use, but also have a very limited service life. Therefore, in order to maintain the rapid and sustainable development of human society, it is necessary to develop safe and abundant clean energy. Controlled nuclear fusion energy is just such an energy source. Because its fuel is abundant in seawater a...
