3D Helmholtz Coil Description

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