3D-Equal Diameter Helmholtz-Coil

3D Equal Diameter Helmholtz Coil Description

The 3D equal diameter Helmholtz coil is a unique, custom-made 3D Helmholtz coil. The three dimensions of the coil are identical, with each having the same diameter, number of turns, uniform area, volume, size, and internal space. The frame is nonmagnetic, making the 3D equal diameter Helmholtz coil especially suitable for use within the shield. The coil can also generate an AC magnetic field. The resistance and inductance of the three axes is the same, so 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 3D equal diameter coil ranges from 1-5Gs.

HC12.5-1

The diameter of the three-dimensional spherical coil is 250mm, 1Gs in each dimension, 35mm in uniform area, 0.1% in uniformity, and 3W in power supply per dimension. Use in a shielded cylinder with a diameter of 300mm.

HC50-1

The diameter of the three-dimensional spherical coil is 1 meter, and the maximum magnetic field strength of a single-axis is 100,000 nT. With the measurement and control software and the high-precision control field power supply, a 1-2nT adjustment step can be achieved. The system is used to simulate the reproduction of geomagnetic field, and it can also be used for active shielding of a geomagnetic environment. Uniform zone 125*125mm², uniformity 0.1%, power supply 20W.

HC15-1

The diameter of the three-dimensional spherical coil is 300mm, producing a low-weak magnetic field of 125KHz for the detection of car keys. The three-dimensional coil constant is the same, as well as the resistance and the number of turns. Uniform zone 70*70mm², uniformity 1%.

HC25-1

The three-dimensional sides are equal to 300mm in length, producing a low-weak magnetic field of 125KHz for the detection of remote key fobs. The three-dimensional coil constant is the same, and the resistance and the number of turns are the same. Uniform zone 70*70mm², uniformity 1%.
