has magnetic north changed

The short answer is yes. However, the change is not as drastic as some may think.

Magnetic north, also known as the north-seeking pole of a magnet, is constantly shifting due to the movement of the Earth's magnetic field. This movement is caused by the convection of molten iron in the Earth's outer core. Over the past century, the magnetic north pole has been moving at an average rate of approximately 55 kilometers per year.

While the movement of magnetic north may seem concerning, it is not a cause for alarm. In fact, this phenomenon is quite common and has occurred throughout the Earth's history. The last time the poles reversed was approximately 780,000 years ago, so we are not due for another reversal anytime soon.
