According to the technical requirements of electromagnetic-eddy current spin-off test for space targets, an electromagnetic generator is designed based on the working principle of the Helmholtz coil, the utility model is composed of a pair of square coils of the same structural size and turns of the coils. The magnetic field generated by the electromagnetic generator is simulated and analyzed by using the Maxwell electromagnetic simulation software, and the distribution of the magnetic field on the X axis, Z axis and the surface of the square coil is observed, the Tesla Meter was used to measure the magnetic field at 27 locations in the central region of the electromagnetic generator. The results show that the uniform magnetic field range, the magnetic induction and the uniformity of the magnetic field produced by the electromagnetic generator can meet the requirements of the electromagnetic eddy current damping test.
