TXEMM | MAGNETIC CHARACTERIZATION
Measure magnetic moment and magnetization versus field for powders, films, and small solids.
Ideal for samples that cannot form a closed magnetic path or require intrinsic magnetic-property characterization.
Understand the behavior, outputs and applications covered by vibrating-sample magnetometry.
What is VSM Testing
A small sample is vibrated within a controlled magnetic field. The induced signal is used to determine magnetic moment as applied field is swept, producing an M-H hysteresis loop.

Best For
VSM testing is ideal for small or irregularly shaped samples that cannot be prepared as ring cores or closed magnetic circuits. It provides high-field M–H characterization for determining key magnetic properties such as Hc, Mr, Ms, susceptibility, and loop shape, making it especially useful for permanent magnets, magnetic powders, thin films, research materials, and comparative material studies.
Connect VSM testing to magnetization, coercivity, remanence and loop-shape data.
Magnetic Susceptibility / Loop Shape
Insight into magnetic response, reversibility, and material behavior.
Coercivity (Hc)
Applied reverse field required to reduce magnetization to zero after saturation.
Remanence (Mr)
Residual magnetization remaining when applied field returns to zero.
Saturation Magnetization (Ms)
Maximum magnetization approached under sufficiently high applied field.
Sample form, mass and mounting affect VSM measurement quality and interpretation.
