Mıknatıs Altını Çeker Mi?

Define Avcısı

Mıknatıslar demir, kobalt, nikel, gibi metalleri çekerken, alüminyum, bakır, altın gibi metalleri çekmez çünkü altın soy metaldir içerisinde altının çekebileceği metal özelliği yoktur bu yüzden mıknatıs altını çekmez. Ayrıca mıknatıs gümüşü de çekmez. Bunların atom numaraları farklıdır.
Bu işin bilimsel açıklaması şöyledir; mıknatısın çektiği maddelere ferromanyetik, çekmediği metallere paramanyetik ve diyamanyetik metaller denir. Altın diyamanyetik metal gurubuna girdiği için mıknatıs altını çekmez.
