Because the metals in the hot center of our earth are moving arround.
Where is the magnetic field around a magnet strongest? Answer: A magnetic field is strongest around the poles. Your welcome! :)
The magnetic field is strongest at the poles of a magnet. Magnetic field strength decreases as you move further away from the poles towards the center of the magnet.
The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most concentrated and where the magnetic force is strongest.
The north and south poles.
Yes, the attractive force of a magnet is greatest at its poles because this is where the magnetic field is strongest. The strength of the magnetic force decreases as you move away from the poles towards the center of the magnet.
True. The magnetic poles move constantly.

Because the earths magnetic poles move around from year to year, and even day to day.
Magnets and magnetic objects are pulled together by magnetic force, which is caused by the alignment of their magnetic fields. This attraction is strongest at the poles of magnets and weaker as you move away from the poles.
This statement is incorrect. Magnetic forces are strongest at the poles of a magnet, where the magnetic field lines are most concentrated. The strength of the magnetic force decreases as you move away from the poles towards the center of the magnet.

At the magnet's north and south poles.
This happens about once every 50 to 100 thousand years and is called a magnetic reversal.It would appear that the self generated magnetic fields formed by rotating bodies all undergo pole reversals. For instance the Sun does this about every 11 years.

Yes, the magnetic forces are strongest at the poles of a magnet because that's where the magnetic field lines are most concentrated. The strength of the magnetic field decreases as you move away from the poles toward the center of the magnet.
The north and south poles.
A magnetic field is generally strongest (most concentrated) at a pole. Note that, while familiar magnets have two poles, it is also possible for a magnet to have more than two. Whether a magnet could have only pole is controversial. The Earth's magnetic field is strongest at the north and south magnetic poles, which are near the north and south geographic poles. The magnetic poles move over time and are generally not located precisely at the geographic poles.
