Magnet inspections

Magnet inspections ensure the quality of the finished product. Inspecting and approving magnets is a prerequisite for proper operation in numerous products and processes.

Test centre Goudsmit Magnetics

Test lab for magnet measurements

Testing can be complex, costly and time consuming. That’s why we have set up a special lab with various test facilities and equipment. In addition, our service engineers can visit on site to test the operation of the magnets in the process line.

With extensive experience and knowledge of magnets, we collect the right information about the operation of the magnet system in your product or manufacturing process. The specially designed test programme reduces the amount of time spent on and the cost of testing.


To save costs and time, we only test what is applicable to certain magnet systems and types. The result is a report that shows whether the product meets the requirements. For audits, this inspection certificate is a requirement.

Why magnet inspections?

The operation and performance of a magnet must be correct to ensure the quality of the end product. 

Inspecting and approving magnets is a prerequisite for proper operation in numerous products and processes. Especially in the food industry, inspection of the magnet systems used is a requirement. Finished products must comply with the international food safety standard HACCP.

How do we conduct magnet inspections?

We check your magnets in the process line annually. In addition to measuring and inspecting the magnetic field strength, we also provide recommendations for process improvements. We record the measurements in an inspection certificate. For audits, this is a valuable report.

Inspections with minimal disruption of your processes.

With a calibrated gauss meter and minimal disruption of your processes, our service engineers carry out on-site measurements. They know exactly how and where to measure and check all installed magnet systems.


We also service other suppliers’ magnets.

For Goudsmit magnets, we then compare the measurements with the original values. If the magnet is from another supplier, we compare the measured magnetic strength with that of a similar magnetic separator.

What does the inspection certificate show?

The inspection certificate shows the location and description of the magnet system. Not only do we assess the current quality and condition, but also the working process.

Our goal is an optimally working magnet system within your manufacturing process.

The following points are part of the inspection report: 

  • Is the magnet placed at the correct location in the process line for optimal results?
  • Does the magnet meet the standard of minimum flux density?
  • What is the physical condition of the magnet system?
  • Are there signs of wear?
  • Is there a risk of obstruction of the product flow or machine damage?
  • Is the magnet safely accessible for cleaning?
  • Is the de-ironing rate optimal?
  • Is the magnet strong enough?
  • Is the magnet being cleaned correctly and often enough?

If there are recommendations for process optimization, we add them to the inspection report.
