DESCRIPTION
Ever wanted to feel like Magneto ? Well, now you sort -of can! Bring the ferromagnetic objects in the world under yo ur control with an Electromagnet The simplest way to make an electromagnet is to get a solenoid, pass some current through it, and then get a piece of soft iron inside the solenoid. When the current is switched off, the electromagnet is no longer, well, magnetic! What this means is that y ou just need to power this here electromagnet with about 5VDC (you don't have to be exact, 4 -6V will work fine) and ka -pow, it's now a magnet. Turn off the power and it reverts back to a normal chunk of metal. Since its a coil, you'll need to use a motor o r solenoid driver with kick -back protection. Our Crickit boards will work great . Please note: electromagnets are specified with "holding force", say 5 Kg / 11 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 1 Kg / 2 lb max. Note that pick -up weight also depends on a flat surface and max surface contact, and the ferromagnetic metal content. A perfe ctly flat steel cube will work great, something oddly shaped or covered in rubber or plastic will not! TECHNICAL DETAILS
