A CRMA component-detail term for the protective layer generally used to protect magnets from corrosion.
Magnet coating is the protective layer around a magnet in the CRMA permanent-magnet context. It is not the magnet itself, not the critical raw material inside the magnet, and not a recycling or recovery process, but it can matter when identifying, removing, or processing magnet-containing components.
This page is anchored in CRMA Article 2, point 56. It belongs with permanent magnet and removal because coating can affect component identification, corrosion protection, and recovery workflows.
Regulation (EU) 2024/1252 establishing a framework for ensuring a secure and sustainable supply of critical raw materials

Reference: Article 2, point 56
Use magnet coating when product or recovery evidence needs to distinguish the protective material around a magnet from the magnet component and the materials being recovered. This helps avoid treating coating records as proof of magnet composition, recycled content, or recovery outcome.
Small component details can change recovery evidence. Minespider keeps magnet coating visible as its own layer so teams can record what protects the magnet without mixing that detail into material classification, component removal, or recycling claims.
