Why Earth's magnetic field is always changing?

Earth's magnetic field is constantly changing and shifting, with the magnetic north pole currently moving towards Siberia and the field's strength fluctuating, though not necessarily leading to an imminent flip.

Earth's magnetic field is not static, but rather in a state of constant flux due to the movement of molten iron in the Earth's outer core.

The magnetic north and south poles are not fixed and gradually shift over time, sometimes even undergoing "excursions" where they wander far from their usual positions.

The Earth's magnetic field is also losing strength, with some studies suggesting a loss of 5% annually, which is roughly 10 times faster than previously predicted.

The movement of the magnetic poles can impact navigation systems, such as GPS, which rely on accurate models of magnetic north.

While the magnetic field is changing, there is no evidence that the current changes are causing any immediate danger to Earth or its inhabitants.
