Q
What does the angle of dip measure? Angle of dip at equator and poles?
A
The angle of dip measures the angle between the Earth’s magnetic field lines and the horizontal plane at a specific location on the Earth’s surface. It indicates how much the magnetic field lines tilt from the horizontal direction. This angle is measured in degrees, ranging from 0 degrees (horizontal field lines) at the equator to 90 degrees (vertical field lines) at the magnetic poles.
