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.
