Three-axis Helmholtz coil DXHC series

magneticAC/DCcircular

Characteristics
Three-axis Helmholtz coil (DXHC series) generates orthogonal X, Y and Z magnetic fields with controllable DC and AC components. It is suited for earth-field cancellation and compensation, geomagnetic environment simulation, magnetic-shielding effect evaluation, EMI simulation experiments, calibration of Hall probes and magnetometers, biological magnetic-field research and studies of material magnetic properties.

Specification parameters

• Model family: DXHC series (multiple radius and field-strength variants).
• Radius examples: models from ~70 mm to 300 mm (DXHC7–DXHC30).
• Center field strength: approx. 2 Gs up to 1000 Gs depending on model.
• Uniformity range: from 5% down to 0.01% (model dependent).
• Homogeneous-sphere diameter examples: Φ10 mm to Φ200 mm (model dependent).
• Per-axis power: ranges from ~5 W to 5000 W depending on model.
• Weights: one-axis and three-axis weights vary by model (see model data).

Additional Notes and Schematic
The product documentation includes a schematic of the magnetic-field control system and examples of 3D shielding-cylinder coils used to obtain low weak fields inside shielding tubes. A three-dimensional shielding-tube coil can combine four axial coils and two groups of saddle (radial) coils, and may be supplemented with first- and second-order gradient-combination coils for improved field shaping.
