Analysis of coils and magnetic materials
Gain documented insights into magnetic fields, material properties, and component performance to support troubleshooting, quality assurance, and product development.
Magnetic analysis is a systematic examination of magnetic fields and the properties of magnetic materials. The analysis is relevant when magnetic components such as coils, permanent magnets, or electromagnets do not function as expected - or when you need documentation of magnetic properties in connection with product development or quality control.
Danish Technological Institute maps magnetic fields in three dimensions, characterizes material properties, and identifies the root causes of deviations, providing you with a solid foundation for making the right decisions.
How can Danish Technological Institute help you?
Danish Technological Institute offers specialized analysis of coils and magnetic materials:
- 3D mapping of magnetic fields - precise visualization of the field around coils and permanent magnets
- Characterization of material properties - determination of key parameters such as saturation magnetization and remanence
- Magnet sizing and dimensioning - calculation and validation of magnet design for your specific application
- Failure analysis - identification of the root causes of unexpected behavior in magnetic components
- Determination of material composition - analysis of the chemical and physical properties of the magnetic material
- Durability assessment - investigation of the stability of magnetic properties over time
- Temperature effects - analysis of how temperature changes affect magnetic performance
Why is magnetic analysis important?
Magnetic components are critical parts in many products - ranging from relays, actuators, and sensors to motors and medical devices. If a magnet’s field properties deviate from specifications, it can lead to malfunctions, reduced performance, or product complaints.
An impartial magnetic analysis provides you with documentation on whether the components meet the specified requirements and pinpoints exactly where any deviation arises - in the material, the design, or the manufacturing process.
When is this service relevant?
Magnetic analysis is relevant in a variety of situations:
- A product is not functioning as expected, and the cause may lie within the magnetic component
- You need to validate or document magnetic properties as part of product development
- You receive magnetic components from sub-suppliers and require impartial quality control
- You experience variations in performance between production batches
- You need to assess whether a magnetic component can withstand the temperatures or mechanical/operational stresses it is exposed to during operation
Impartial analysis from Danish Technological Institute
Danish Technological Institute is an independent, non-profit research and technology organization with specialized expertise in magnetic analysis and material characterization. This means that you receive results that are independent of supplier or manufacturer interests, and which can be used directly in your quality management, product documentation, or warranty/claim cases.
