The explanation of a Compass

When you're lost in the woods, you best chance of finding your way might be a tiny magnet. A magnet is a compass that point North the small magnetic pin in the compass is so that it can spin freely inside and respond to our plant's magnetism. A compass needle points toward the top of the Earth's Magnetic Field and it is giving explorers sense of the direction. A compass points North because all the magnets have two poles, a North pole and South pole, and the North pole of the one is magnet is attracted to the South pole to the another magnet. The Earth is a magnet that can interact because with the other magnets in it's way, so the North end of the compass magnet it is drawn to align with the Earth's Magnetic Field. The Earth's Magnetic North Pole attracts the "north" ends to the another magnet and it is technically the "South Pole" of our planet's magnetic field. While the compass is a great tool for navigation it doesn't always point to North. This is why because the Earth's Magnetic North Pole it is not the same as "true north", or the Earth's geographic North Pole. The difference between true North and the North heading on a compass is an angle called declination. The declination varies from one to another because the Earth' Magnetic Field is not uniform. The compass needle point away from both of the geographic North Pole and the magnetic North Pole.
