has magnetic north changed

the position of magnetic north is constantly changing. In fact, it has been changing throughout history, and will continue to change in the future.

The reason for this has to do with the nature of the Earth's magnetic field. The Earth is itself a giant magnet, with a magnetic field that is generated by the movement of molten iron in the planet's core. The position of the magnetic north pole is determined by the interaction of this field with the magnetic fields of other celestial bodies, including the sun and the moon.

Over time, the positions of these celestial bodies change in relation to the Earth, causing the position of magnetic north to shift. In addition, the Earth's magnetic field is not static - it can fluctuate and even reverse polarity over thousands of years.

Currently, the position of magnetic north is moving at a rate of about 40 kilometers per year, which is relatively rapid compared to historical standards. This means that the position of magnetic north today is significantly different from what it was even a few decades ago.

For those of us who rely on magnetic navigation systems or other magnetic products, this can be a cause for concern. However, the good news is that modern technology has made it easier to track the position of magnetic north in real time, allowing us to update our maps and devices accordingly.
