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.

Now that the Sun is approaching the peak of its magnetic cycle, when solar storms - blasts of electrically charged magnetic clouds - are most likely to occur, no one can predict how it will behave.

The sun is currently approaching what's known as solar maximum, the peak of our star's roughly 11-year cycle of magnetic activity.
