A radio signal has both electrical and magnetic properties.(无线电信号既具有电的特性也具有磁的特性。)
When the magnetic field is at its strongest, and sunspots at their most plentiful, they cluster close to the equator.(当磁场最强,太阳黑子最丰富的时候,它们会聚集在赤道附近。)
The electrically charged gas particles are affected by magnetic forces.(带电的气体粒子受磁力的影响。)
They also offer a set of kitchen utensils like a magnetic saucepan that can be cooked using electromagnetic wave transmission technology.(他们还推出了一系列的厨房用具,比如可以利用电磁波传导技术进行烹饪的磁性炖锅。)
The fact that sunspots are magnetic fields accounts for their dark appearance.(太阳黑子是磁场的事实解释了它们的黑色外观。)
Astronomers did eventually figure out what sunspots had to do with magnetic fields.(天文学家最终确实发现了太阳黑子与磁场的关系。)
Western Europeans had also developed and put into use the magnetic compass, which helped when clouds obliterated both the Sun and the stars.(西欧人也已经发明并且使用了磁罗盘,当云彩同时遮住了太阳和星星时,它就能起作用。)
The mineral is weakly magnetic.(这种矿石有轻微的磁性。)
A thin magnetic stripe (magstripe) is all that stands between your credit card information and the bad guys.(你的信用卡信息和坏人之间只隔着一片细细的磁条。)
