The 3DXHC9-3 Three-Dimensional Helmholtz Coil has undergone comprehensive performance testing to ensure compliance with technical specifications. Below are the key findings from the evaluation conducted on November 08, 2024.
Magnetic Field Performance
Using the DX-F2031 power supply and DX-330F fluxgate magnetometer, the coil demonstrated stable magnetic field generation under controlled conditions (ambient temperature: 16.0°C, lead length: 3m):
Field Strength (at 1A input):
- X-axis: 3.456 Gs
- Y-axis: 3.608 Gs
- Z-axis: 3.421 Gs
Uniformity (tested at 0.2A input):
- X-axis (φ70mm area): Max 68,768nT, Min 68,453nT (-0.96% uniformity)
- Y-axis (φ55mm area): Max 72,214nT, Min 72,054nT (-0.16% uniformity)
- Z-axis (φ80mm area): Max 68,405nT, Min 68,251nT (-0.25% uniformity)
The Y-axis exhibited the highest uniformity, suitable for precision applications requiring minimal field variation.
Electrical Parameters
Resistance measurements (adjusted to 20°C and 85°C reference temperatures) confirmed stable electrical behavior:
- Resistance @20°C:
X-axis: 2.414Ω | Y-axis: 3.749Ω | Z-axis: 6.337Ω - Resistance @85°C:
X-axis: 3.136Ω | Y-axis: 4.870Ω | Z-axis: 8.231Ω
