False. Opposite poles attract. Same poles repel.
They indicate that the Earth's magnetic field has undergone shifting of the positions of it's poles several times in the past.
Scientists indicated that the seafloor was spreading, so the poles "reverse"
The magnetic field reverses polarity. North becomes South.

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.

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.
every 250,000 years :)
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
Yes, Earth's magnetic field is weaker at the poles compared to the equator. This is because the magnetic field lines converge at the poles, making the field strength weaker in those regions.
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.

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.
