Magnet Square - 0.125"

These are very small rare earth magnets - 0.125" 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. Don't let the photo fool you - these are very small magnets.

Activates the reed switch (shown below) at a distance of about 1cm.

Sold in single units.

    I'm confused. These magnets do not look like they are 0.125" cubes. More like 0.25" cubes. Please could someone confirm?

    Don't forget to emblazon these with "do not swallow" stickers...

    I suppose you might be "safe" as long as you don't market them as toys. (I never did get a couple cubes of the buckyballs or cubes before they were recalled...) :'(

    Wait, so how big are these, really? Next to the quarter, they do indeed look to be about 0.125", but according to the ruler picture, it's over 0.25" to a side...

    Would this magnet paired with a Hall Effect Sensor or a Insulated Reed Switch be able to work mounted to the front wheel and fork on my MC?
    (I'm looking into building a wireless speedsensor).
    The distance from fork to wheel is some inches. (10 cm or so)

    I'm using these to trigger a Hall effect sensor. A bit more sensor sensitivity is nice on these since they pack less punch than a bulkier magnet, but they're still plenty strong if you have good sensitivity and a reasonable sensing distance.

      Could you share numbers? It would be great to know what cm distance (even roughly) it takes for this magnet to trigger a Hall Effect sensor (itself rated to switch at 0.5-9.5mT or 5-95gauss).

        I tested this magnet with a Hall effect sensor rated at 85G (see the test, this magnet at 1:20), and it switched at about 0.5cm.

    Could i use these to trigger a Hall Effect Sensor?
