Parameter configuration method for multipole magnetic trap coil based on electric power balance

The present invention provides a parameter configuration method for a multipole magnetic trap coil based on electric power balance. The multipole magnetic trap system consists of three hagfish coils and a compensation coil. The method comprises: taking a minimum magnetic induction intensity in the multipole magnetic trap as a target; taking poloidal balance of an electromagnetic force on the multipole magnetic trap as a constraint condition; and calculating and configuring the number of ampere turns of the multipole magnetic trap coil by using a genetic algorithm, to obtain an optimum number of ampere turns of the hagfish coils and the compensation coil. The method provided by the invention can reduce a electrodynamic force among multilevel magnetic trap coil, avoid a structural distortion of the multipole magnetic trap coil caused by the electrodynamic force, and improve operation reliability of a multipole magnetic trap apparatus.
