ac electromagnet
常見(jiàn)例句
- Rotating magnetic field is not caused by mechanical methods, but in AC pass in a few of the electromagnet, the nature of its magnetic cycle of change can be seen as rotating magnetic field.
轉(zhuǎn)動(dòng)磁場(chǎng)并不是用機(jī)械方法造成的，而是以交流電通于數(shù)對(duì)電磁鐵中，使其磁極性質(zhì)循環(huán)改變，可看作為轉(zhuǎn)動(dòng)磁場(chǎng)。
