I use these in my piezo transducer/microphone housing.
They work well, but I might try the 4mm next time.
I am happy with my purchase - and will shop again with AMF Magnetics. thanks.

This neodymium magnetic disc has a diameter of 3mm and a height of 1.5mm. It has a magnetic pull force of 208 grams. It is identified by the AMF Magnetics part number D-D3H1.5-N50ni.
This tiny disc is certainly one of the smallest rare earth discs in our product range. Perfect for craft projects, the extremely strong hold provided by the Neodymium magnetic material goes a long way in making up for its diminutive size. Although nobody would consider this little disc heavy duty it really does hold its own when compared to the strength of other types of permanent magnets. Small rare earth magnets such as these can be found in a surprisingly large array of electronic equipment, from speakers to electric motors.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
