| Abstract: | It analyzes the eddy current,the distribution of the induced magnetic field and the electromagnetic force on the lower hybrid wave launching antenna on the superconducting tokamak HT 7 by using finite element circuit method.A new iterative algorithm is developed to analyze the coupled magnetic field.The method and results obtained are helpful to study the eddy current and electro magnetic force on metal plate placed in rather complicated electro magnetic environment. |

| Keywords: | lower hybrid wave launching antenna finite element eddy current iteration |
