Stray field demagnetizer
Stray field demagnetizers with flux-regulating cores are ideal for demagnetizing a wide variety of materials. They are often referred to as plate, table or surface demagnetizers and are particularly suitable for flat objects. Demagnetization is carried out by a stray field that is generated via the core. Two pole plates serve as flux amplification cores, whereby the stray flux is optimally bundled in the area of the pole gap.
How does the stray field technology work?
The magnetic stray field refers to the field component that occurs on the outside of a coil or a flux-conducting material. The strength of the stray field decreases significantly with increasing distance from the field source. Thanks to this property, stray field demagnetizers are particularly efficient when demagnetizing flat objects with thin walls.
However, the stray field principle is only suitable to a limited extent for larger, bulky components, as the full magnetic flux of such components cannot be completely captured.
Advantages of stray field demagnetizers
- Targeted demagnetization: Ideal for flat, thin-walled workpieces.
- Efficient flux regulation: Flux amplification through pole plates maximizes the effect.
- Compact design: Perfect for use in workshops or production lines.
If you want to reliably demagnetize flat objects, stray field demagnetizers are the optimal choice.
The devices we use are operated either directly from the mains and therefore in a continuous process or with power modules in pulsed or continuous operation.
We create specific designs for your needs
Standard demagnetizing yokes
Our demagnetizing yokes (without pole plates) offer an effective width of 160 mm to 600 mm. Other dimensions are also available on request to meet individual requirements.
The demagnetizing yokes can be easily connected to the standard mains frequency: 230 VAC or 400 VAC at 50/60 Hz. This simple and flexible installation makes them ideal for use in various industrial applications.

LM power modules: Extended range of functions for controlled demagnetization
The LM power modules extend the range of functions of a standard demagnetizer to the level of a controlled system. These modules offer a wide range of applications and ensure maximum safety and efficiency.
Manual operation: safe and user-friendly
In pulse mode, demagnetization is performed by simply placing the object on the yoke coil and pressing the pulse button on the power module. You benefit from several advantages:
- Safe personal protection: the pulse function prevents direct contact with the objects during demagnetization, minimizing electromagnetic fields.
- Programmable pulses: Demagnetizing pulses can be set so that they fall well below the personal protection limits - a major advantage over conventional 50 Hz mains frequency yokes.
Automated operation: Efficiency in production
Our devices can be easily integrated into automated processes. They communicate smoothly with higher-level control systems via an interface. We work closely with you to configure the optimum process for your individual demagnetization requirements.
Technological possibilities:
- Demagnetization by sine pulse with very high field strength
- Continuous pulse process (for continuous flow)
- Continuous process with low frequency for greater general penetration depth
- Use of two opposite yokes (i.e. a double yoke)
- Short pulses (approx. 1,000 ms)
- Various monitoring functions
