Chapter 27, Problem 1Q
A compass needle is not always balanced parallel to the Earth’s surface, but one end may dip downward. Explain.
Expert Solution & Answer
To determine
The compass needle is not always balanced parallel to the Earth’s surface.
Answer to Problem 1Q
The Earth’s magnetic field lines are not parallel to the surface of the Earth
Explanation of Solution
The Earth's magnetic field is not always parallel to the surface of the Earth. It may have a component perpendicular to the Earth’s surface. This is because the earth is not a uniform circle.
The compass tends to line up with the local direction of the magnetic field, so one end of the compass will dip downward.
Conclusion:
The Earth’s magnetic field lines are not parallel to the surface of the Earth
