Equal Diameter 3D Helmholtz Coil
There is also a common application that generates an AC magnetic field. Since the resistance and inductance of the three axes are the same, the same AC power supply can be used for three-axis switching to control the magnetic field with a voltage.
The maximum magnetic field in each dimension of the three-dimensional equal-diameter coil can be 1Gs ~ 5Gs.
