Consider the following statements

1. The angular difference between the North Pole and the Magnetic North Pole is fixed and known as the magnetic declination.

2. According to one of theories, the magnetic poles shift due to changes in the Earth's core in response to charge particles emitted by the sun hitting the earth's magnetic field.

Explanation:

First statement is incorrect as over the last 150 years, the magnetic pole has crept north over 1000 kilometers. Scientists suggest it migrates about 10 kilometers per year and can even flip from pole-to-pole. Lately, the speed has accelerated to about 40 kilometers per year and could reach Siberia in a few decades. So, the angular difference between the North Pole and the Magnetic North Pole is not fixed. Magnetic variance, or declination, is the difference between geographic north and magnetic north.

Second statement is correct as the magnetic poles shift due to changes in the Earth's core in response to charge particles emitted by the sun hitting the earth's magnetic field.
