Learn how to interact with this file using the Ouro SDK or REST API.
API access requires an API key. Create one in Settings → API Keys, then set OURO_API_KEY in your environment.
Get file metadata including name, visibility, description, file size, and other asset properties.
Get a URL to download or embed the file. For private assets, the URL is temporary and will expire after 1 hour.
Update file metadata (name, description, visibility, etc.) and optionally replace the file data with a new file. Requires write or admin permission.
Permanently delete a file from the platform. Requires admin permission. This action cannot be undone.

They get their power from the Nd2Fe14B crystal, which gives high magnetic density and good resistance to demagnetizing forces. These magnets are made by carefully controlled powder metallurgy: pure materials are melted in a protective environment, turned into fine powders, and then pressed with a magnetic field to align the magnetic direction. They are then vacuum sintered and heat treated to make the material dense and stable. Grain size, how different phases are spread, and the chemistry at grain boundaries all affect performance, especially at higher temperatures. Techniques like diffusion with heavy rare-earth elements can boost high-temperature performance while keeping rare-earth use efficient. Because they can corrode easily, coatings such as nickel, zinc, epoxy, or multiple layers are often added for protection. These magnets power motors in EVs, wind turbines, automation, medical devices, and other energy-efficient systems.
