The TXEMM-BH01 automatic hysteresisgraph/hysteresis loop tracer is a computer system used for measuring the magnetic properties of soft magnetic materials at frequencies ranging from DC to 1KHz following ASTM standard test procedures, such as ASTM A342, ASTM A343, ASTM A773 and ASTM A977. Testing of magnetic properties is necessary for the selection, production and quality control of magnetic materials used in many industrial applications such as the electric motors, transformers, sensors, speakers, and recording media. TXEMM provides wide range of magnetic properties testing for both the “soft” and “hard” magnetic materials.

Soft magnetic materials/soft magnetic composites are characterized by high magnetic induction, high magnetic permeability, low coercivity, and low loss. The key to accurately determine these parameters is to ensure measured sample forms magnetic close circuit (no end magnetic poles). One example is to make a sample in a ring shape wounded with primary and secondary coils for generating field and detecting magnetic flux.

The magnetic properties that TXEMM can measure for you include:

• Saturation magnetization
• Maximum, initial and other permeabilities
• Remanence and coercive field
• Hysteresis loss
• DC and AC B-H curve
• Epstein frame and ring samples testing for soft-magnetic materials
• Demagnetization curve of permanent magnet (testing temperatures up to 200°C)
