The Sun's magnetic poles reverse approximately every 11 years during the solar cycle. This phenomenon is part of the Sun's complex magnetic behavior, which influences solar activity, including sunspots and solar flares. The pole reversal occurs when the Sun's magnetic field undergoes a complete flip, with the north and south poles switching places. This cycle can vary slightly in duration and intensity but typically aligns with the solar cycle's peak activity.
To reverse the poles produced in a coil, you can simply reverse the direction of the current flow through the coil. This will change the magnetic field orientation and reverse the poles.

Only in the angle of incidence.
There is nothing -_-
every 250,000 years :)
The Earth's magnetic poles do not reverse every year. On average, the magnetic poles reverse every 200,000 to 300,000 years. The last reversal happened around 780,000 years ago.

25 days for a rotation at the equator, 34 days for a rotation near the poles.

poles of an armature can be reversed by the arrangement of split-rings
The windings of a transformer do have poles, which alternate in polarity in step with the A.C. magnetising current. As the polarity of the poles reverse, so too does the direction of the magnetic flux within the transformer's core.
