Technical Specifications

Spatial flux free, miniaturized MNP sensor, embedded magnetic measurement

Usage & Applications

Internal magnetic field characterization of laminated magnetic cores (spatial flux free measurement).
Miniaturized magnetic sensing (< 200 µm) for embedded and homogenization analysis.
Local hysteresis cycle B_a(H_surf) measurement on individual laminations.
Comparison of simulation predictions with local measurements in magnetic cores.

Operating notes:

Probe requires gentle surface contact; do not scratch laminations.
Hall sensor supply: +6 V DC. Output pre-amplified (x100) and low-pass filtered at 20 Hz.
Keep probe clean and recalibrate against a reference steel sample before each campaign.
