- The simulation of satellite orbit magnetic field produced by two pairs of Helmholtz coils is studied.
- The optimum space of square Helmholtz coil was evaluated on the basis of mathematic deduction.
- The electron displacement meets non-linear relation when the radius of Helmholtz coil is given.
- In this paper, a triple-coil magnetic field is designed, which is better than Helmholtz coil not only in uniformity but in intensity.
- An approach to a compound equipment composed of a three axe Helmholtz coil system set inside a magnetic shielding room has been made.
- Using the slider to drive a metal bar to cut perpendicularly the uniform magnetic field in the center of a Helmholtz coil, induction electromotive force could be produced.
