Magnets

Rare‑earth magnets such as neodymium‑iron‑boron provide very high holding force in very small volumes, making them ideal for attaching tools, securing components on metal benches or actuating reed switches in compact assemblies. Their compact square and ring forms allow precise placement where space is limited, while larger ceramic discs offer a more uniform field suitable for general‑purpose mounting or lightweight load‑bearing tasks. Key considerations include material type, which influences strength and temperature tolerance, and geometry, which affects the distribution of magnetic flux and ease of integration with adhesives or brackets. Choosing the appropriate size and composition ensures reliable performance across robotics, sensing and everyday prototyping projects.
