Neodymium N38 Countersunk Ring Magnets – Pair 10x6.5x4mm

Magnets make fantastic little additions to your 3D print or Electronics projects with interesting uses limited only by your imagination. We love stocking different types and form factors of Magnets to fit your experiments. These Neodymium N38 Countersunk Ring Magnets are sold as pairs of north and south magnets, featuring a countersunk hole. Each pair is perfect for strong holding power of N38 strength. Countersunk magnets are designed to work in pairs and be mounted to any surface with a nail through their 6.5mm holes. Interesting and unique Mechanics/CNC and electronics project ideas are possible using their attraction or repel properties.

Although these magnets feature a 6.5mm hole in the centre, they are polarised axially from flat side to flat side. As such, this pair of Neodymium N38 Countersunk Ring Magnets are great for creating semi-permanent solenoids, Hobbyist levitation experiments, jeweller trays, latches for doors and enclosure lids, or even for building unique toys like DIY magnetic dart guns or even full-scale magnetic trampolines – although these particular ring magnets may be a bit small for a trampoline. These Neodymium N38 Countersunk Ring Magnets have an outer diameter of 10mm and thickness of 4mm, making them perfect for smaller applications like the snap lock on your 3D printed jewellery box.

Please Note: These units are priced in pairs, but have a minimum order quantity of 5. By ordering 5 pairs, you will receive 10 individual units – 5 north magnets and 5 south magnets. This is to help professionals and contractors in their pricing structures, while avoiding unnecessary shipping costs, so as to ensure the best possible price for each and every customer.

Typical Applications for Neodymium Countersunk N38 Magnets:

Ring magnets are excellent tools that are most often used in Electronics like Disk-Based Hard Drives, audio equipment, Motors and generators, as well as a host of other hobbyist and industrial grade use cases. However, what we like most about ring magnets is that you can use them to create your own magnetic snap-circuits, by soldering leads onto washers and inserting the washers into the centre hole of the magnet. Then, when the Magnets attract towards each other, the washers get forced tightly together to close the circuit, making attachment and detachment of the circuit as easy as possible.
