Rare Earth Magnets

By now many people have been exposed to wonders of neodymium rare earth magnets; they've been around in various forms since the mid-1960s. As the years go by, these magnets have become more and more powerful and less and less expensive. Gone are the days where you'd have to tear apart an old hard drive to scavenge the magnets out of it. Now, they are readily available in a huge variety of shapes and sizes for all types of projects.
Rare earth magnets are commonly used to hold or lift things, which is understandable given that they can lift more than 500 times their own weight in steel. The MAGCRAFT brand of rare earth magnets has a wide selection of strong, good-quality magnets and is available at local hardware stores and online. I found the half-inch disc magnets (NSN0702) particularly useful.
