Magnet Ring - 3/16 ″

Description

These are small rare earth magnets - 3/16 ″ rings. Composed of Neodymium / Iron / Boron (NdFeB), these magnets are curiously strong and make for a great way to attach tools to a metal workbench, hold small children to a fridge, and as a trigger for reed switches. This one small ring can easily hold a piece of paper to your fridge.

We found these rings to be very useful for connecting PCBs together. These rings are conductive and can act as magnetic connector between widgets. You need to secure the ring to the PCB (screws and rivets have been shown to work).

Sold in single units.
