Earth's magnetic poles have reversed on average about every 250,000 years over the past 20 million years. However, the timing and frequency of these reversals are not completely regular and can vary widely. The last magnetic pole reversal occurred about 780,000 years ago, so we are currently overdue for the next one based on historical averages.
The strength of Earth's magnetic field is strongest at the magnetic poles, which are not necessarily aligned with the geographic poles. The magnetic field is weakest at the magnetic equator.
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.

The phenomenon you're referring to is known as geomagnetic reversal or magnetic pole reversal. This occurs when the Earth's magnetic field flips its polarity, causing the magnetic north and south poles to switch positions.
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.

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.
This is known as magnetic reversal when earth's magnetic poles change places.
Magnetic Reversal
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.
No, Earth's magnetic poles are not located exactly on its geographical poles. The magnetic poles are located slightly off-axis and can shift over time due to changes in the Earth's magnetic field.

No, it is not true. The magnetic poles may be influenced by Earth's rotation, but they are certainly not defined by it.
