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。

The magnetic forces will push it towards the centre, but gravity will pull it downwards until an equilibrium point is attained.

These use an electric current to heat and ablate a material, producing a charged gas that can then be accelerated in one direction in a magnetic field to push the cubesat in the other direction.
