Material:Magnets
From CoMakingSpace Wiki
You can salvage very strong magnets from old hard disk drives. Patrick also embedded a few ball-shaped neodymium magnets into his 3D printed bike light holder.
Most ferrous metals (those containing iron) as well as cobalt and nickel are magnetizable. High-quality stainless steel is not!
Sourcing
We only have some salvaged hard drive or speaker magnets on site right now so you may want to buy your own:
- Supermagnete.de seems to be a good source, recommended by André
