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.
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.
If the Earth's magnetic poles were to reverse, it would not have any direct effect on the brain. The reversal would mainly impact magnetic compasses and certain animal navigation systems that rely on the Earth's magnetic field for orientation. Our brain's functioning would not be directly affected by this event.

There is no scientific evidence to suggest that the gravitational poles will switch. The Earth's magnetic poles can undergo a reversal, but this does not affect the gravitational poles. The gravitational pull on Earth is primarily due to the mass of Earth itself, not the orientation of its magnetic field.
As Earth's magnetic poles reverse, the magnetic orientation of rocks formed during the reversal captures the changing magnetic field. This phenomenon is known as magnetic polarity reversal, where new volcanic rocks or sediments align with the current magnetic field, preserving a record of the past orientations. Over time, these rocks display alternating patterns of magnetic polarity, which scientists can study to understand the history of Earth's magnetic field and tectonic activity.
The process of the reversal of the Earth's magnetic poles is called a magnetic flip. This occurs every 4 or 5 times per million years.
every 250,000 years :)
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
The like poles refer to two magnetic poles that are the same (i.e., north-north or south-south) and repel each other due to their similar magnetic orientation. This phenomenon is based on the principle that like magnetic poles repel each other, while opposite poles attract.
