Abstract

The invention discloses a spherical three-dimensional uniform magnetic field coil for an SERF atomic magnetic field / inertial measurement sensor. The spherical three-dimensional uniform magnetic fieldcoil is composed of three spherical coils which are identical in configuration and perpendicular to one another, wherein magnetic fields in the x direction, the y direction and the z direction are generated respectively, the defect that the length-diameter ratio in a cylindrical coil is too large can be overcome, the size of the magnetic field coil is reduced, and meanwhile it can be guaranteed that the uniform performance of the three-dimensional magnetic field is consistent.

Description
