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.

# Retrieve file metadata
file = ouro.files.retrieve(file_id)
print(file.name, file.visibility)
print(file.metadata)Get a URL to download or embed the file. For private assets, the URL is temporary and will expire after 1 hour.
# Get signed URL to download the file

ouro.files.delete(id=file_id)NdFeB composition defines the elemental structure of neodymium-iron-boron magnets, which are among the most widely used high-performance permanent magnets. These materials are mainly composed of neodymium (Nd), iron (Fe), and boron (B), forming the Nd₂Fe₁₄B crystal phase that determines their strong magnetic behavior. Neodymium contributes magnetic anisotropy, enabling high coercivity and magnetic stability. Iron provides high magnetic saturation, which supports strong magnetic output. Boron stabilizes the crystal lattice, ensuring consistent material performance. In industrial production, additional elements such as dysprosium or terbium may be introduced to improve thermal stability and resistance to demagnetization. Because of their high magnetic energy density and compact size, NdFeB magnets are widely applied in electric motors, renewable energy systems, automation equipment, and electronic devices. A clear understanding of NdFeB composition supports proper material selection, performance optimization, and reliable operation across various technical applications.
