■ NORMAL AND REVERSE FIELD

#Magneticfield

◇ The Earth's field has alternated between periods of normal polarity, in which the predominant direction of the field was the same as the present direction, and reverse polarity, in which it was the opposite.

◇ In Normal Polarity, Earth’s North Magnetic Pole is the South Pole of its Magnetic Field. In Reverse Polarity, Earth’s North Magnetic Pole is the North Pole of its Magnetic Field.

■ COMPASS

#Magneticfield

◇ A compass point north because all magnets have two poles, a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet.

◇ The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field.

◇ Because the Earth's Magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.

◇ While a compass is a great tool for navigation, it doesn't always point exactly north. This is because the Earth's magnetic North Pole is not the same as "true north (Earth's Geographic North Pole)."

◇ Although the magnetic declination (deviation from true north) does shift with time, this wandering is slow enough that a simple compass remains useful for navigation.
