Permanent Magnet Stabilizing and Calibrating

Permanent Magnet Stabilizing and Calibrating

Permanent magnets are utilized in a wide range of commercial and industrial applications, many of which require these magnets to function in a highly stable and consistent manner. Variables such as temperature, and demagnetizing fields will impact performance, but these effects can be mitigated through stabilization or calibration. Our new whitepaper, Permanent Magnet Stabilizing and Calibrating, explains how these techniques work, why they are sometimes necessary, and what to expect as a result.

You’ll discover how stabilization can be used as a pre-treatment against temperature change in the application, as well as to combat the presence of demagnetizing fields. Different methods may be used depending on your specific needs.

Calibration addresses variance in magnetic (flux) output that can occur during permanent magnet production. The treatment process creates a consistently tighter tolerance range than normally seen, and can even reduce out-of-spec-high magnets to an acceptable flux output.

The automated manufacture of any product inevitably results in a range of quality. Stabilization and calibration provide a means to create permanent magnets of greater consistency and tighter performance variation. HSMAG can help you determine and implement the best stabilization or calibration method to ensure the resulting product characteristics meet your requirements. Contact us to get started.

This whitepaper is intended for manufacturers that use permanent magnets and need magnets or assemblies that are magnetically stable over the expected temperature range of use or those manufacturers requiring magnets to perform within a very tight tolerance of flux output.

Magnetic fields produced by permanent magnets vary with temperature in a reversible way unless key limits to performance are exceeded. Even within the acceptable-use temperature range, minor irreversible changes in magnetic output can occur. This effect can be mitigated by stabilizing the magnets.

In a second case, the variability of flux output from magnet-to-magnet may be too large to satisfy a demanding application. It is possible to pre-treat magnets so that entire lots of material perform within a tightened range of flux output. This is often called calibration.

This paper will explain what these processes are, how they are performed and the resulting product characteristics.
