Three-dimensional equal diameter coil

The three-dimensional equal diameter coil is a three-dimensional Helmholtz coil independently developed by our company. Its characteristics are: the coil diameters of the three dimensions are the same, the number of turns are the same, and the wire diameter is the same; the uniform area has the same volume, small appearance, large internal space, and the overall frame is non-magnetic and metal, especially suitable for use in the shielding cylinder. Another common application is to generate an AC magnetic field. Since the resistance and inductance of the three axes are the same, the same AC power supply can be switched between three axes to control the magnetic field with voltage. The highest magnetic field per dimension of the three-dimensional equal-diameter coil can be 1Gs~5G.

3HLD

Y50-1

 The diameter of the three-dimensional equal-diameter coil is 1 meter, and the maximum single-axis magnetic field strength is 100,000 nT. With the measurement and control software and high-precision field control power supply, it can achieve an adjustment step of 1-2 nT. This system is used for the simulation and reproduction of the geomagnetic field, and can also be used for the active shielding of the geomagnetic environment. The uniform area is Φ125*125mm, the uniformity is 0.1%, and the power supply is 20W.
3 3HLDY15-1 The three-dimensional equal diameter is 300mm, which produces a low-weak magnetic field of 125KHz, which is used for the detection of car remote control keys. The three-dimensional coil constants are the same, and the resistance and the number of turns are the same. The uniform area is Φ70*70mm, and the uniformity is 1%.
4 3HLDF15-1 The three-dimensional side length is equal to 300mm, and a low-weak magnetic field of 125KHz is generated, which is used for the detection of automobile remote control keys. The three-dimensional coil constants are the same, and the resistance and the number of turns are the same. The uniform area is Φ70*70mm, and the uniformity is 1%.
