Makers, developers and electronics enthusiasts may be interested to know that a new 5 V electromagnet providing a 10 kg holding force is now available to purchase from the Adafruit online store. Priced at $14.95 the small electromagnet, Adafruit Product ID 3874 draws 0.4 Amps at 5V.
Adafruit explains a little more about the specifications and pickup load. “Please note: electromagnets are specified with “holding force”, say 10 Kg / 22 lb. This is not how much weight they can pick up! Divide the holding force by 5-10 to get a rough estimate of how heavy a thing it can pick up. So in this case, about 2 Kg / 4 lb max. Note that pick-up weight also depends on a flat surface and max surface contact, and the ferromagnetic metal content. A perfectly flat steel cube will work great, something oddly shaped or covered in rubber or plastic will not!”
