变压器是根据电磁感应的原理制成的.在在闭合的铁芯柱上面绕有两个绕组,一个原绕组,和一个副绕组.当原绕组假上交流电源电压时.原饶组流有交变电流,而建立磁势,在磁势的作用下铁芯中便产生交变主磁通,主磁通在铁芯中同时穿过,{交链]一.二次绕组而闭合由于电磁感应作用分别在一,,二次绕组产生感应电动势,

The transformer is made according to the principle of electromagnetic induction. In the closed wound on the iron core column has two windings, a primary winding, and a secondary winding. The primary winding when the false AC power supply voltage. The original Rao group a alternating current flow, and the establishment of magnetic potential, generates alternating magnetic flux in the main magnetic the role of EMF in the core, through the main magnetic flux in the core at the same time, {chain.] two windings and closed due to electromagnetic induction, respectively in a two winding induced electromotive force,

至于为什么它可以升压,和将压呢..那就需要用楞次定律来解释了.感应电流产生的磁通,总阻碍圆磁通的变化,当原磁通增加时感应电流的产生的磁通与与原磁通相反,

As for why it can boost, and the pressure.. you need to use Lenz's laws to explain. Flux induced current, the changes of total flux when the original round block, flux increases the induced current and the magnetic flux generated with opposite magnetic flux,
