Magnet Ring - 3/16"

Sparkfun's 3/16" ring magnets are small yet incredibly potent. Crafted from Neodymium/Iron/Boron (NdFeB), these rare earth magnets are impressively strong. They're perfect for attaching tools to a metal workbench, securing small items to your fridge, or even acting as a trigger for reed switches. Even a single ring can easily hold a piece of paper to your fridge.

These rings aren't just for home use, they can also be utilised in your tech projects. They've proven to be particularly useful for connecting PCBs together. Thanks to their conductive nature, these rings can act as a magnetic connector between widgets. However, you will need to find a way to secure the ring to the PCB, with screws and rivets having been shown to work well.

Each purchase includes a single unit of the magnet ring.
