Correct Answer - Option 2 : 90°
Concept:
Dip:
- It is the inclination of the magnetic needle with the horizontal.
- This angle varies at different points on the Earth's surface. Positive values of inclination indicate that the magnetic field of the Earth is pointing downward, into the Earth and negative values indicate that it is pointing upward.
- 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.
- At all the other places, the angle of dip is between 0 and 90 degrees.
