Magnets are fantastic little tools that can be used for an incredible range of different applications, with different types and polarisations that add even more potential to these magical metal-movers. This is why we are eager to tell you about these Neodymium N38 Ring Magnets, with 15mm Outer Diameter, 5mm Inner Diameter and 4mm thickness, as these magnets feature a 5mm hole in the centre, which can lead to very interesting Mechanics/CNC and electronics project ideas.

Although these magnets feature a 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.
