- Demagnetizing field - Wikipedia
The demagnetizing field, also called the stray field (outside the magnet), is the magnetic field (H-field) [1] generated by the magnetization in a magnet The total magnetic field in a region containing magnets is the sum of the demagnetizing fields of the magnets and the magnetic field due to any free currents or displacement currents
- Demagnetization: Techniques And Applications - physicsclass. blog
Demagnetization involves reducing or eliminating the magnetic properties of a permanent magnet Techniques include thermal (heating), AC (applying alternating current), or shock (applying a sharp magnetic pulse)
- Nondestructive Evaluation Physics : Magnetism
Also, many stationary magnetic particle inspection units come with a demagnetization feature that slowly reduces the AC in a coil in which the component is placed A field meter is often used to verify that the residual flux has been removed from a component
- How to Demagnetize a Magnet - ThoughtCo
Demagnetization randomizes the orientation of magnetic dipoles Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal

- Demagnetisation - loss of magnetisation - supermagnete. de
Demagnetisation can be achieved by strong impacts, heat or a strong magnetic field with reversed polarisation To demonstrate this in an experiment, you simply need to expose a ferrous material to a strong external magnetic field
- Demagnetization - Basics and Know-How | Maurer Magnetic AG
Demagnetisation is achieved by using the alternating magnetic field to move the evenly aligned elementary magnets into homogeneous disorder and to generate as fine a domain structure as possible The demagnetisation power that must be applied for this is defined by the field strength
