Lesson 1: Earth's magnetic field & magnetic elementsMagnetic dip & horizontal component of Earth's field
The angle made by the Earth's magnetic field with the horizontal, in the magnetic meridian, is called the dip. The dip is zero close to the equator and 90 degrees close to the magnetic poles. The dip angle is useful in calculating the horizontal and vertical components of the Earth's fields. Created by Mahesh Shenoy.

So, if I live at 40 degrees, 30 minutes North latitude, how do I calculate the degree of magnetic dip for my location?(2 votes)- If I'm not wrong, you have to use that "vertical compass" that he showed. The north part of the needle should point downwards (since you live in the northern hemisphere) making an angle with the horizontal (at your place). This is angle is what is called as dip.(3 votes)
