How To Get Free Powerful Neodymium Magnets From Old HDD

Neodymium magnets from hard disks are strong, rare-earth magnets typically found in the actuator assembly of the drive. They are used to move the read/write head with precision. These magnets are coated with a thin layer of nickel to prevent corrosion and are usually attached to a steel backing plate, which makes them even stronger due to the ferromagnetic properties of the steel.
Uses for Hard Disk Neodymium Magnets
1. DIY Projects & Science Experiments - Magnetic levitation, electric generators, or magnetic couplings.
2. Magnet Fishing - Small-scale retrieval of metallic objects.
3. Holding & Clamping - Can be used in tool holders, fridge magnets, or hidden latches.
4. Metal Detection & Sorting - Can help in separating ferromagnetic materials.
5. Repurposing for Motors & Generators - Can be used in small homemade wind turbines or alternators.
6. Wireless Power Transfer & Induction Experiments - Useful in electromagnetic projects.
