Physics 2001 JAMB Past Questions - Question 35: What is the angle of dip at the magnetic equator?

Correct Answer

B

Explanation

The angle of dip at the magnetic equator is typically very close to 0 degrees. At the magnetic equator, the Earth's magnetic field lines are nearly horizontal to the Earth's surface, causing the magnetic field to be almost parallel to the ground. This means that a compass needle will be nearly horizontal, or level, when placed at the magnetic equator, and the angle of dip, also known as the magnetic inclination, is essentially zero.

As you move away from the magnetic equator towards the magnetic poles, the angle of dip increases, and the magnetic field lines become more inclined to the Earth's surface. At the magnetic poles, the angle of dip is at its maximum, close to 90 degrees, which means that the magnetic field lines are almost vertical.

It's important to note that the Earth's magnetic field is not perfectly aligned with the geographic poles and can vary over time and location due to the complex nature of the planet's magnetic field.
