變壓器的主要構成為鐵芯及漆包銅線。
當 變壓器送電時，會產生磁力線，而且這些磁力線會在鐵芯裡面跑，鐵芯有磁阻，會發熱，熱就是損失。鐵芯雖然很薄，但總是還有些厚度，所以，磁力線在鐵芯裡面 跑，多少會轉彎、打圈圈，就叫渦流，也是損失。磁力線在鐵芯裡面跑，鐵芯有磁阻，會讓磁力線慢下來，就是磁滯，也是損失。鐵損與渦流損失、磁滯損失的平方 成正比，無電源時，即無鐵損。
銅損：當電流流經漆包銅線時，漆包銅線有電阻，會發熱，熱就是損失。銅損與電流平方成正比，無負載電流時，即無銅損。

.為什麼鐵芯用多片薄的鋼片組起來？
A.如果用一整塊的鐵來作鐵芯，則鐵損更大，磁力線在鐵芯裡面跑，多少會轉彎、打圈圈，就叫渦流，也是損失。其實鐵芯每片之間都有加絕緣漆，目的就是希望磁力線不要跑到隔壁的鐵芯(矽鋼片)。站在電的立場矽鋼片越薄越好(渦流越小)，但太薄時，則機械強度會不夠。
