This invention discloses a method, system, and storage medium for calculating the self-torque of a bitter coil, relating to the field of water-cooled magnet technology. The method includes obtaining the basic parameters of each coil in a water-cooled magnet; dividing the conductors in the upper or lower half of the coil into several annular grids; determining the coordinates of the grid center points based on the basic parameters; calculating the total radial magnetic field component at each grid center point; using the integral of the current density distribution of each grid over the single-turn cross-sectional area of ​​the coil, which equals the target current flowing through the coil, to solve for the current density distribution at each grid location; calculating the helix angle sine of the current helix path within the grid based on the helix path plane of the grid; calculating the axial current density component of each grid based on the current density distribution at each grid location and the corresponding helix angle sine; and calculating the electromagnetic torque of the coil when the target current flows through it based on the total radial magnetic field component and the axial current density component of each grid.

The present application relates to a kind of high-speed moving conductive object magnetic rotation method and device, utilize space cross magnetic field or multi-angle cross magnetic field, axial current is induced on the surface of conductive object, axial current is acted on by magnetic field force in cross magnetic field, and torque is generated to conductive object, so as to rotate along its own axis to conductive object.Cruciform cross magnetic field can be with magnetic field or electric field, high-speed moving conductive object can be single material or composite material, can be all conductor or partially have conductivity.The present application has the characteristics of high adaptability, long life, fast rotation and safe and reliable.
