Overview

Adjustable Magnetic Field permanent magnet units provide a continuously tunable DC magnetic field by mechanically changing the pole air gap or the magnetic-circuit geometry. They keep the advantages of permanent magnets (no excitation power) while enabling precise field setting for laboratory and industrial use where a stable, adjustable DC field is required.

Technical characteristics / specifications

• Adjustment mechanisms: change pole air gap or modify magnetic-circuit width/geometry; some designs adjust field without moving relative pole positions.
• Adjustment modes: manual mechanical control or motorized (reducer/stepper) for precise positioning and fine adjustment (precision can reach ~1 Gs in low-field models).
• Magnetic capability: models cover ranges from low gauss (tens of Gs) up to ~1.2 T depending on model and gap.
• Air gap ranges: typical adjustable spans from ~5 mm to 100 mm depending on model.
• Pole surface diameters: available variants from small (Φ8 mm) to large (Φ40 mm, Φ50 mm, Φ100 mm, Φ150 mm) to suit sample size and uniformity needs.
• Form factors & weights: compact laboratory footprints with weights from ~5 kg to ~13 kg for selected models.
• Field uniformity & resolution: selected low-field models provide good spatial uniformity in small volumes and 1 Gs-level adjustment accuracy; some support continuous zero-crossing adjustment.
• Typical applications: laboratory testing, material characterization, magnetic-field dependent experiments, anti-interference testing for meters, and any DC adjustable-field requirement where permanent-magnet reliability and no excitation power are advantageous.
