摘要
实验采用大气压放电产生等离子体,利用永磁体组合产生的轴向发散磁场来约束等离子体,直观地展现了磁场约束等离子体的实验现象,实验方法简单、便捷,对于提高大学生的等离子体基础知识和创新实验能力具有重要作用。
This experiment uses atmospheric pressure discharge to produce plasma,and uses the axial divergent magnetic field generated by the combination of permanent magnets to restrict the plasma,which intuitively shows the experimental phenomenon of magnetic field restraining the plasma.The experimental method is simple and convenient,which plays an important role in improving the basic plasma knowledge and innovative experimental ability of college students.
