Three Dimensional Equal Diameter Helmholtz Coil 3 Axis Helmholtz Coil for Sale
Threedimensional equaldiameter coils are threedimensional 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 nonmagnetic metalfree, 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 threeaxis switching to control the magnetic field with a voltage.
The maximum magnetic field in each dimension of the threedimensional equaldiameter coil can be 1Gs~5G.
