1D Helmholtz Coil Description

1D Helmholtz coils have a large uniform volume and an open space for easy operation. They can realize 1D, 2D, and 3D combined magnetic fields, as well as AC and DC magnetic fields. The current in the 1D Helmholtz coil and the magnetic field maintain a linear relationship.
