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.
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
True. The magnetic poles move constantly.
Earth's magnetic field reverses its polarity irregularly, with north and south magnetic poles switching places every few hundred thousand years. This phenomenon is known as geomagnetic reversal. The last complete reversal happened around 780,000 years ago.
Geographic poles refer to the Earth's axis points where it meets the surface (North and South Poles), while magnetic poles refer to points where the Earth's magnetic field is the strongest. These poles do not align exactly; the geographic poles are fixed, while the magnetic poles can shift position over time due to changes in the Earth's magnetic field.

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.
True. The magnetic poles move constantly.
Magnetism leaves particles in molten metals lined up with north and south poles (magnetic poles, not the Earth's poles). Over time different layers of rock show that the N-S and S-N poles have switched, with S pointing in one direction and S pointing in a different direction depending on the age of the rock.
Earth's magnetic poles have reversed many times in the past due to changes in the Earth's molten outer core. As the molten metal moves, it generates the Earth's magnetic field. Over time, this movement can cause the magnetic field to weaken, flip, and establish a new polarity. The process of pole reversals is a natural part of the Earth's geophysical history.

The Earth's magnetic poles do in-fact 'wander' over the years. Estimates put the movement of the North Pole at 34-37 miles (55 and 60 kilometres) per year. The magnetic poles are not always directly opposite each other. There is a good article on Wikipedia with more information - search for 'north magnetic pole'.
There are no "magnetic north poles", only one. (There is also a magnetic south pole.)The reason is that the magnetic poles change over time.
Geographic poles refer to the Earth's axis points where it meets the surface (North and South Poles), while magnetic poles refer to points where the Earth's magnetic field is the strongest. These poles do not align exactly; the geographic poles are fixed, while the magnetic poles can shift position over time due to changes in the Earth's magnetic field.
The freely suspended magnet will align itself vertically, with its north pole pointing directly downward towards the Earth's magnetic pole. This is because the magnetic field lines are vertical at the magnetic poles.
