The angle of dip at the magnetic poles of the earth is 90°. The angle of dip at any location is the angle the Earth’s total magnetic field B makes with the magnetic meridian’s horizontal direction. The angle at the Earth’s magnetic field lines form with the flat is referred to as magnetic dip, dip angle, or magnetic inclination. The dip angles at the poles and the equators are 90° and 0°, respectively. The region where the dip is vertical is referred to as the magnetic pole. At the magnetic poles, the horizontal intensity is zero, the dip needle is vertical (dip=90 degrees), and a compass does not indicate direction.

What is the angle of dip at the magnetic pole of the earth?
The angle the Earth’s total magnetic field B creates with the magnetic meridian’s horizontal direction is known as the dip angle at any location. Specific places on the Earth’s surface can distinguish it. Magnetic dip, dip angle, or magnetic inclination are all terms used to describe the angle the Earth’s magnetic field lines make with the horizontal. The dip angle at the specified position is determined by the angle formed by the horizontal and final movements of the dip needle.
Important Points on Angle of dip:
At the magnetic equator, the dip angle is zero as the dip needle relaxes horizontally. The rise of dip is crucial for identifying the components of the Earth’s magnetic field region. The dip needle rests vertically to achieve a 90° dip angle at the Earth’s magnetic poles. Everywhere else, the dip angle ranges from 0° to 90° degrees.
- About 11 degrees separate the dipole’s axis from the Earth’s axis of rotation.
- Straight parallel lines represent the lines of forces caused by the Earth’s horizontal magnetic field.
- At the south magnetic pole, the dip ranges from -90 degrees to +90 degrees (at the north magnetic pole).
