If you’ve ever taken the time to simply play with magnets and enjoy all of the weird and wonderful scientific (and non-scientific) experiments that you can do with Magnets, then you will surely understand what our in-house magnet fanatic means when he says “Magnets are additive”. This notion comes from the fact that magnets really are useful in an extremely wide range of different applications, from 3D Printing to simple electronics enclosures, and as our catalogue of magnets that we stock grows, the possibilities for producing unique projects from sometimes farfetched ideas becomes ever more realisable. This is why we warmly welcome these Neodymium N38 15x9.5x3mm Ring Magnets to our catalogue, and we hope you enjoy this new addition as much as we have enjoyed playing with these magnets.

Although these magnets feature a 9.5mm hole in the centre, they are polarised axially from flat side to flat side. As such, these 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.

Typical Applications for Neodymium N38 Ring 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.
