Applications:

These Neodymium block magnets are magnetized through the 1/2″ length, meaning the magnetic poles are located on the smaller 3/8″ x 3/8″ ends. Shaped almost like a “square cylinder”, they offer a compact yet powerful form factor.

Their unique geometry and strong pull make them ideal for precision applications, including sensors, closures, assemblies, and other setups where a focused magnetic field at the ends is preferred. Versatile and easy to handle, these blocks are a favorite for both industrial and DIY projects.
