If you reverse the connection between the wire and the battery poles, the direction of the magnetic field around the wire will also reverse. This is because the flow of current through the wire determines the direction of the magnetic field according to the right-hand rule.
Scientists predict that Earth's magnetic field will eventually reverse, meaning the magnetic north and south poles will switch places. This process happens over thousands of years and is a natural occurrence in the planet's history. However, there is no definitive timeline for when this reversal will occur.
Scientists indicated that the seafloor was spreading, so the poles "reverse"
False. Opposite poles attract. Same poles repel.

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.
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.
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.
If you reverse the connection between the wire and the battery poles, the direction of the magnetic field around the wire will also reverse. This is because the flow of current through the wire determines the direction of the magnetic field according to the right-hand rule.
every 250,000 years :)
When opposite poles meet, they attract each other due to the difference in magnetic orientation. This attraction causes the magnetic fields to interact and align with each other. If they are strong enough, they may snap together in a forceful manner.
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
