What is a disadvantage of not demagnetizing a part after magnetic particle inspection?

Not demagnetizing a part after a magnetic particle inspection can lead to several significant issues, particularly the risk of interference with other manufacturing processes. When the part remains magnetized, it can attract ferrous debris or contaminants present in the manufacturing environment, which could lead to contamination of the part or other components in close proximity. This attraction can also hinder proper assembly with other parts, creating potential misalignments or operational issues.

Furthermore, residual magnetism may affect machine parts or tools used in subsequent processes, leading to inaccurate machining or damaging delicate components. Hence, it is crucial to demagnetize components post-inspection to ensure they do not interfere with their intended function during later stages of production. This highlight of risk due to residual magnetism underlines why proper demagnetization is critical following inspection.
