TXEMM | MAGNETIC CHARACTERIZATION
Measure coercivity, remanence, saturation, loop shape, and hysteresis under controlled DC excitation
Designed for ring cores, laminations, ferrites, and soft magnetic materials that require full-loop hysteresis characterization under DC excitation.
Understand the behavior, outputs and applications covered by DC B-H loop characterization.
DC B-H Loop Testing
A DC excitation is applied to the sample and magnetic flux density (B) is measured as a function of magnetic field (H) to produce a hysteresis loop.

Best For
DC B-H loop testing is most useful when you need a complete view of hysteresis behavior, including coercivity and remanence, or when material performance at low frequency or DC conditions matters most.
Connect DC B-H testing to coercivity, remanence, saturation and loss data.
Loop Area / Hysteresis Loss
Area enclosed by the loop is proportional to energy loss per cycle.
Coercivity (Hc)
Field required to reduce magnetic flux density to zero after saturation.
Remanence (Br)
Residual flux density remaining at zero field after saturation.
Saturation (Bs)
Maximum flux density achieved at high magnetic field.
