For a sunspot to form on the solar surface, the magnetic field needs to attain a certain strength to push the surface plasma aside, exposing the solar interior as a cool spot — a sunspot.
在太阳表面，磁场强度必须强到能推开表面的等离子体，将温度较低太阳内部的暴露在外，形成一个太阳黑子。
These methods all can be used to solve the magnetic aberration hi the conventional push-pull converter.
这两种方式均可以解决传统推挽直流变换器存在的偏磁问题。
Although this behavior might seem paradoxical, it is actually quite a simple matter to make electrons oppose the "push" of the applied electric and magnetic fields.
这个行为虽然看起来很诡异，但事实上要使电子反抗外加电场及磁场的“推力”，道理却相当简单。
It's a maglev keyboard that actually floats the keys, using magnetic force to provide tactile resistance when you push them.
这个键盘的按键通过磁力悬浮在键盘上，比普通键盘手感更好，而且能根据按键力度的不同改变按键的抗阻。
