GEOLOGY

Detailed explanation-1: -The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth’s Northern Hemisphere at which the planet’s magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down).

Detailed explanation-2: -At the magnetic equator, the dip needle rests horizontally at an angle of zero degrees while, at the magnetic poles, the magnetic needle rests vertically, at an angle of 90 degrees.

Detailed explanation-3: -The inclination of the Earth’s field is 90° (downwards) at the North Magnetic Pole and-90° (upwards) at the South Magnetic Pole. The two poles wander independently of each other and are not directly opposite each other on the globe.

Detailed explanation-4: -However, at (and near) the magnetic poles, the fields of force are vertically converging on the region (the inclination (I) is near 90 degrees and the horizontal intensity (H) is weak). The strength and direction tend to “tilt” the compass needle up or down into the Earth.

Detailed explanation-5: -The Geographic North Pole is defined by the latitude 90° N and is the axis of the Earth’s rotation. The Magnetic North Pole is where the Earth’s magnetic field points vertically downward.
