Three-dimensional equal-diameter coils are three-dimensional Helmholtz coils designed exclusively by our company. Its characteristics are: the three dimensions of the coil diameter is equal, the same number of turns, the same diameter; uniform area volume, small size, large internal space, the overall frame of non-magnetic metal-free, especially suitable for use in the shielding tube. 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~5G.
