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.

ouro.files.delete(id=file_id)Sintered NdFeB magnets are a leading type of permanent magnets used in many industries because they offer high magnetic energy and can be made in compact sizes. Their strength comes from the crystal structure of neodymium-iron-boron, which gives high remanence and resistance to demagnetization. The magnets are made through a careful powder metallurgy process: materials are melted in a protected atmosphere, cooled quickly, and milled into fine powder; during shaping, an external field aligns the magnetic grains to create anisotropy; then high-temperature sintering densifies the material and forms strong grain boundaries. Fine control of grain size, phase makeup, and diffusion at boundaries boosts coercivity and temperature stability, with methods like heavy rare-earth diffusion used to improve performance while managing rare-earth use. Because they corrosion easily, surface coatings such as nickel, epoxy, or multi-layer systems protect them in harsh environments. They are used in EVs, wind turbines, motors, robotics, medical devices, and precision equipment.
