Home »
Our magnetic measurement business serves an important role in technology, product development and engineering applications for many large and small businesses including many Fortune 100 companies, Universities, Medical institutions and many more in both domestic and international markets.
ARkival’s VSM Group is considered as the premier magnetic contract measurement company with expertise in all aspects of magnetic materials and their applications.
Our large, prestigious and established client base seeks our magnetic measurement expertise that extends from magnetic field measurements to materials and devices with many applications in the form of magnetic solids, liquids and thin films.
We maintain a well-equipped Magnetic Testing Laboratory that provides full service magnetic testing capability for all your magnetic applications, material evaluations and product testing. Our supporting Physics and Chemistry labs are fully equipped to service the needs of all types of magnetic applications, magnetic nanotechnologies, magnetic products and their evaluations, component make-up and performance analyses. Our services include sample preparations, magnetic evaluation, supporting analysis, modeling and simulations among many others client requirements.
ARkival’s VSM’s and torque magnetometers and a multitude of Hall Effect probes provides for magnetic measurements of magnetic materials used for all applications. Our independent measurement laboratory tests magnetic materials including thin films, ferrites, powders, concretes, magnetic liquids and gels, nanotechnology products, magnetic platings, particles, beads and tapes, discs, wires and permanent magnets (both iron-based and rare-earth materials). Our services include simple magnetic parameter data, quality and assurance data, magnetic analysis, custom measurements and full analytic reports.
HYSTERESIS LOOP
ARKIVAL MEASURES AND REPORTS HYSTERESIS LOOP CURVES WITH KEY MAGNETIC MATERIAL PARAMETERS
The Hysteresis curve identifies and reports important magnetic properties of magnetic materials. The curve is often referred to as the ‘B-H loop’ and expresses the relationship between two important magnetic parameters, the letter (B) is used for the magnetic moment of the material and the letter (H) for the applied magnetic field (or force) for the measurement.
The Hysteresis curve also identifies several key parameters as most materials demonstrate increasing magnetic moment with stronger magnetic fields. Typically, a point in the measurement is obtained when the material is fully magnetized and additional increases in the magnetizing field produces little or no change in magnetic moment. The material has then reached the point of magnetic saturation.
The data from the Hysteresis curve is used to report the following magnetic parameters of the material:
- The magnetic saturation of the material
- The Retentivity or the remanence, residual magnetism or Retentivity after the applied field is removed.
- The coercivity (The force required to remove the residual magnetism from the material) often called the coercive force or coercivity.
- The definition of Permeability, µ -A property of a material that describes the ease or difficulty in which a magnetic moment is generated in the material.
