Physics 2014 JAMB Past Questions - Question 41: The magnitude of the angle of dip at the equator is

Correct Answer

A

Explanation

the angle of dip is the angle which magnetic compass needle makes with the horizontal, it is zero at a magnetic equator and 90 degree at the magnetic poles
The magnitude of the angle of dip at the equator is approximately zero degrees. The angle of dip, also known as the inclination or magnetic dip, refers to the angle between the Earth's magnetic field lines and the horizontal plane. At the equator, the magnetic field lines are nearly parallel to the Earth's surface, resulting in a very small or negligible angle of dip.
