What are the advantages of using fluorescent magnetic particles?

Fluorescent magnetic particles are designed to emit visible light when exposed to ultraviolet (UV) light, which significantly enhances defect detection during the magnetic particle inspection process. This property allows inspectors to see finer surface irregularities and defects more clearly than with non-fluorescent particles. The glow emitted by these particles under UV light increases contrast against the background, aiding in identifying critical flaws that may otherwise go unnoticed. This improved visibility is crucial in ensuring the integrity and safety of the materials being inspected, making fluorescent particles particularly advantageous in applications where precision is essential.

While other options address factors such as cost or cleaning ease, the distinguishing feature that makes fluorescent magnetic particles particularly beneficial is their ability to provide superior visibility under UV light, directly impacting the effectiveness of the inspection process.
