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.
At the poles
At the poles.
When the sun's magnetic poles switch positions, it represents a natural process in the sun's magnetic field known as solar magnetic field reversal. This event occurs approximately every 11 years, marking the peak of the solar cycle. During this time, the magnetic field weakens, flips, and then strengthens again, impacting space weather and solar activity.
Only in the angle of incidence.

During a magnetic pole reversal, the magnetic orientation of rocks changes to align with the new orientation of the Earth's magnetic field. This means that the magnetization of rocks will also reverse during a geomagnetic field reversal event.
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.
Mercury
25 days for a rotation at the equator, 34 days for a rotation near the poles.
