Well, now you sort-of can! Bring the ferromagnetic objects in the world under your control with an \u003cstrong\u003eElectromagnet\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 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!\u003c\/p\u003e\u003cp\u003eWhat this means is that you just need to power this here electromagnet with about \u003cstrong\u003e5VDC\u003c\/strong\u003e (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 or solenoid driver with kick-back protection. Our Crickit boards will work great.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note: electromagnets are specified with \"holding force\", say 2.5Kg \/ 5.5lb\u003c\/strong\u003e. \u003cem\u003eThis is not how much weight they can pick up!\u003c\/em\u003e \u003cstrong\u003eDivide the holding force by 5-10 to get a rough estimate of how heavy a thing it can pick up\u003c\/strong\u003e. So in this case, about 1 lb. 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!\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cul\u003e\n\u003cli\u003eNominal Voltage: 5V DC\u003c\/li\u003e\n\u003cli\u003eCurrent Draw: 0.22 Amps at 5V\u003c\/li\u003e\n\u003cli\u003eHolding Force: 2.5 Kg \/ 5.5 lb\u003c\/li\u003e\n\u003cli\u003eDiameter: 20mm \/ ~0.78\"\u003c\/li\u003e\n\u003cli\u003eCenter Diameter: 8mm \/ ~0.3\"\u003c\/li\u003e\n\u003cli\u003eHeight: 15mm \/ ~0.59\"\u003c\/li\u003e\n\u003cli\u003eLead Length: 270mm \/ ~10\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Weight: 25.1g \/ 0.9oz \u003c\/p\u003e\n\u003cul id=\"product-files\"\u003e \u003cli\u003e\nDiagram \u003c\/li\u003e\n\u003c\/ul\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48623811657946,"sku":"haf1789679256487","price":6.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/5v-electromagnet---25-kg-holding-force-p2015_1.jpg?v=1789679260","url":"https:\/\/memoryfoamwear.shop\/products\/5v-electromagnet-25-kg-holding-force-p2015","provider":"My Store","version":"1.0","type":"link"}
