Measuring laboratory Magnetic Measuring Technology

We offer magnetic properties testing of permanent magnets and soft-magnetic materials in our comprehensively equipped magnetic test and measurement laboratories. Some types of measurements can be performed on-site at a customer location. The equipment used in our laboratories can also be purchased for use in your own facility.

Here is a summary of the many types of measurements which we can offer:

Measurements at magnet systems

  • Magnetic field strength
  • Magnetic flux density
  • Linear scans
  • Surface scans
  • Rotational scans (e.g. around a motor rotor, 3D-field mapping)

Properties of permanent magnets:

  • Demagnetization (B,H) curve, sample temperatures of -40 °C to +200 °C
  • Magnetic moment (Helmholtz coil)
  • Working (operating) point determination
