HDD Head-Actuator Rare Earth Sintered Neodymium Magnet
Rare Earth magnets (also known as Sintered Neodymium magnets) are 5 to 7 times stronger than Ferrite Magnets and offer the greatest value for money. They provide high energy, maximum efficiency and extreme stability when exposed to other electromagnetic fields. For this reason they are commonly used in engineering, HDD, electronics and medical fields.
Rare Earth Magnets are the most advanced magnet with superior performance and are a logical choice when extra strength in a reduced size is important. Available in Nickel, Zinc, Epoxy or Gold plated varieties.

Scavenging parts from old, discarded electronics is a skill every maker should hone. Old hard drives in particular are stuffed with useful components and greeblies that you can incorporate into other projects. They’re also just plain fun to open up (at least once you find those hidden screws manufacturers hide under their labels to prevent tampering).
The folks at iFixit have a great teardown worth checking out that walks you through the process of opening a hard drive. The critical tool you’ll need is a set of Torx drivers or bits (typically T4, T6, and T8).
If there’s a pearl to be plucked from a hard drive, it’s the large, super strong Neodymium (rare earth) magnet. Manufacturers typically tuck these magnets under a permalloy bracket in the corner of the drive nearest the actuator arm that moves across the disc.
In the video shown here, you’ll see where to locate the magnet, how to remove the bracket, and how to use a vise and wrench to get a purchase on the strong magnet and remove it. A standard 3.5” internal hard drive should yield two crescent-shaped magnets. 16 x 8 x 3 mm Small Block Neodymium Domino Magnets with Rubber Coating
