【Abstract】 A new method to get uniform magnetic field-improved Helmholtz coils is proposed by replacing Helmholtz coils by three coils with the same radius connected in series. Simple formulas are derved for the magnetic field of the improved Helmholtz coils. Numerical results demonstrate that the uniform region of magnetic field for the improved Helmholtz coils is larger than that of Helmholtz coils.更多还原
