磁石馬達(dá)
商品摘要
本產(chǎn)品利用帶鐵芯的通電線(xiàn)圈具有磁性的特性,并用干簧管作開(kāi)關(guān),當(dāng)磁鐵轉(zhuǎn)到干簧管附近,線(xiàn)圈通電有磁與輪上磁鐵相斥,輪子轉(zhuǎn)動(dòng)并且磁鐵離開(kāi)干簧管斷開(kāi)電路,如此往復(fù)從而使轉(zhuǎn)輪轉(zhuǎn)動(dòng)...本產(chǎn)品利用帶鐵芯的通電線(xiàn)圈具有磁性的特性,并用干簧管作開(kāi)關(guān),當(dāng)磁鐵轉(zhuǎn)到干簧管附近,線(xiàn)圈通電有磁與輪上磁鐵相斥,輪子轉(zhuǎn)動(dòng)并且磁鐵離開(kāi)干簧管斷開(kāi)電路,如此往復(fù)從而使轉(zhuǎn)輪轉(zhuǎn)動(dòng)。通過(guò)實(shí)驗(yàn)了解電磁鐵與磁鐵相斥的工作原理及其應(yīng)用。
