How do compasses work? Artwork: Earth behaves as though it has a giant bar magnet built inside it. But the magnet is the opposite way around to how you might think, with its south pole up near Earth's actual (geographic) north pole and vice-versa. A compass needle points north because the north pole of the [...]
North Magnetic Pole - "Magnetic North" redirects here. For other uses, see Magnetic North (disambiguation). The North Magnetic Pole is the wandering point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, [...]
Polar Reversals: South-Pole Pointing Compass Imagine your compass pointing south instead of north. Compass If you were alive to see it 800,000 years ago, it would have been the Magnetic South Pole. It takes 200,000 to 300,000 years for Earth’s magnetic field to flip polarity. Flipping polarity means the lines of attraction that enter the [...]
What is the Magnetic North Pole? The Earth is one big magnet. The Magnetic North Pole (also known as the North Dip Pole) is a point on Ellesmere Island in Northern Canada where the northern lines of attraction enter the Earth. A compass needle rests freely in its casing so it can maneuver itself. When [...]
What is the Geographic (True) North Pole? The Earth rotates on the geographic north and south poles. The geographic north and south poles are where lines of longitude (meridians) converge in the north. The south and north pole are directly opposite to one another. The North Pole is located in the middle of the Arctic [...]
Magnetic North Pole Basically, the Magnetic North Pole is where a compass points. This is not the northernmost point on the globe. It is a point in the Arctic that is always on the move, reacting to magnetic changes in the Earth’s core. Every few years scientists venture into inhospitable territories to locate the pole. [...]
