Where is the North Magnetic Pole located?

Where is the North Magnetic Pole located?

• A. Alaska
• B. Hudson Bay, Canada
• C. Greenland
• D. Antarctica

Answer: (B)

The North Magnetic Pole is the point on Earth where the magnetic field lines enter the surface vertically. It isn’t fixed like the geographic North Pole because the Earth's magnetic field is generated by fluid motion in the outer core, which slowly shifts over time. Over the years, this wandering has moved the pole across the Arctic toward North America, and it’s been located near Hudson Bay, Canada for many updates. The other locations—Alaska, Greenland, or Antarctica—do not correspond to the current vertical-field point.
