  • eddy current 嘛~

  • 的確不需要通電

    只要任意的金屬管(不一定是鐵管)加上一顆磁鐵就可以了

    是冷次定律

    落下的過程中,管壁會產生感應電流跟反向的感應磁場

    磁鐵就會受到一個向上的力

  • @Ds3509 這麼厲害就PO出來讓大家瞧瞧,別指會說三道四!!

  • @Ds3509 不通電會吸住= =

  • 楞次定律

  • 傻子...不過就是電磁感應罷了...

    只要把磁鐵丟入金屬長管就可以了...

    根本不需要通什麼電..

  • 這因該是線圈八 通電之後產生 磁力 丟磁鐵他會產上 如果是N級往下丟

    他會產生 像上的N級 所以同性相斥 它就會慢慢掉下去

  • @jok1438 我都知道...人地叫你破解他嗎???
