Description: Replacement: None. We only had a limited supply of these. This page is for reference only.

These are small rare earth magnets - 0.187" cubed. 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.

Activates the reed switch (shown below) at a distance of about 2cm.

Note: We have a limited supply of these, once they’re gone, they’re gone!

Sold in single units.
